Discussion about ionic bond and covalent bond

DICUSSION ABOUT Ionic bonds and covalent bonds



In the class, Fania, ayu and lita. They are discussing last week's lesson entitled "ionic bonds and covalent bonds" 

Fania: friends, I still do not understand the difference between conventional bonding and ionic bondingAyu: The difference is just a different form of bond right?

 Lita: no, But the ion bond is trebentuk due to transfer or the handover of electrons between atoms attached 

Ayu: bonding? What is the bond? 

Lita: Bonding is an attractive forceAyu: oh so

 Lita: Simply the meaning of ionic bonds is the bond between two kinds of ions (cations and anions) by Coulomb's electrostatic forces. However, for example for complex compounds [Fe (H2O) 6] 2, Fe2 central ions with H2O molecules are also largely bound by electrostatic forces between central ions with fixed negative dipole generated by the traveling molecule.

 Fania: Can you explain the example?

Lita: For example on table salt (sodium chloride). When sodium (Na) and chlorine (Cl) join, sodium atoms lose their electrons, forming cations (Na), while chlorine atoms receive electrons to form anions (Cl-). These ions then attract each other in a 1: 1 ratio to form sodium chloride.

    Na Cl → Na Cl- → NaClAyu: So what kind of species is the ion species?Lita: From the book I read, one that I remember Species without valence electronsHydrogen ion H, may be seen as the only example of a species without valence electrons, although its existence is stabilized in solvent solvent form, ie as hydronium ion, H3O, in water.

Fania: Not only that, but there are 6?

lita: if you want more details, you can see in chemistry book volume 1

.Fania: yes, Can you give one more example of ionic bonds

 Ayu: Let me give you an example. Examples of ionic bonds: NaF, K2S, MgO, AlF3Bonding of bonding ions that occur between metal elements and non-metals

 Fania: ok, then what conventional bond is it? , Can it be explained again?

Lita: A covalent bond is a type of chemical bond that has the characteristic of a split pair of electrons (shared electron usage) between bonded atoms. In short, the stability of attraction and repulsion formed between atoms when using electrons is known as covalent bonding.
Example :

 

Fania: does covalent bond have an isomer
Lita: yes, the isomers have isomers
Ayu: What is the attraction of ionic bonds?
Fania: a positively charged nucleus, predominantly above the positive charge of other nuclei, effectively causing one atom to transfer its electron to the other.
Ayu: Well friends, I already understand it, thanks for the discussion

      Easily soluble in polar solvents.

      not at all , Here are examples of compounds that exhibit both types of chemical bonding:

      NaNO3 - sodium nitrate
      (NH4)S - ammonium sulfide
      Ba(CN)2 - barium cyanide
      CaCO3 - calcium carbonate
      KNO2 - potassium nitrite
      K2SO4 - potassium sulfate

      In ammonium sulfide, the ammonion cation and the sulfide anion are ionically bonded together, even though all of the atoms are nonmetals. The electronegativity difference between ammonium and the sulfur ion allows for an ionic bond. At the same time, the hydrogen atoms are covalently bonded to the nitrogen atom.

      Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded.

      A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds.

      In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. The atoms have different electronegativity values from each other.

      There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

      onic Binary Compounds

      For naming an ionic binary formed from one metal element and one

      Nonmetallic element, initially written the metal name without modification and

      Naming of non-metallic element 'ida'.

composition of matter in chemistry

ATOM             An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element . Every solid , liquid , gas , and plasma is composed of neutral or ionized atoms. Atoms are very small; typical sizes are around 100  picometers (a ten-billionth of a meter, in the short scale).                Atoms are small enough that attempting to predict their behavior using classical physics - as if they were billiard balls, for example - gives noticeably incorrect predictions due to quantum effects . Through the development of physics, atomic models have incorporated quantum principles to better explain and predict the behavior. Most of the Universe consists of matter and energy . Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of at

    Examples of Chemical Reactions in Everyday Life  When you mix chemicals in a lab, it's easy to see the reaction, but lots of chemical reactions occur in the world around you every day. Martin Leigh/Getty Images Chemistry happens in the world around you, not just in a lab. Matter interacts to form new products through a process called a chemical reaction or  chemical change . Every time you cook or clean, it's  chemistry in action . Your body lives and grows thanks to chemical reactions. There are reactions when you take medications, light a match, and take a breath. Here's a look at 10 chemical reactions in everyday life.

report : Identification of a Compound using Melting and Boiling Points

Identification of a Compound using Melting and Boiling Points Introduction  One of the primary methods used to characterize a new compound is the physical determination of its normal melting and boiling points.   The “normal” melting and boiling point is the temperature at which a substance melts or boils when the barometric pressure is 760 mmHg or 1 atm.   In this experiment we will first calibrate our thermometers using ice and water, whose normal melting and boiling points are well characterized as 0.0 ° C and 100.0 ° C, respectively [1] .   Following this, we will measure the normal melting and boiling points of an unknown compound.   We will use this data to determine the identity of our unknown from a list of possible unknown samples and physical data from the Chemical Handbook [2] .   Experimental Procedure  As described in the lab manual, [3] ice was placed in a beaker and warmed until approximately 50% had melted.   The temperature of the ice/water mixture
