  • Atomic weight doesn't increase in a constant manner with respect to elements increase in atomic number.
  • Where as while taking about atomic number it increases in a specific manner so it's easy to arrange a periodic table .

At before Duberinor,Mendeleev tried to use atomic weight but they failed .

The chemical properties are mainly dependent on the electrons, or in some cases the charge of the protons, which is independent of the number of neutrons.So,they are arranged by increasing atomic number…

Answer:

Covalent bonding

Explanation:

In covalent bonding, the electrons are shared to fill the octet rule (8 electrons in valence shell). CCl4 tends to do covalent bonding because the the 4 valence electrons are Carbon are shared with the Chlorine atoms so that each chlorine atom has a full octet and chlorine shares its electrons to fill the octet of carbon.

Also, since carbon and chlorine are both non-metal, non-metal things exhibit covalent bonding thus this is covalent bonding as well. Ionic boding is for metal and non metal pair where electrons are transferrred, in our case, electrons are shared, they are not transferred.

The net ionic equation for the reaction between aqueous sulfuric acid and aqueous sodium hydroxide is ________.
Dennis_Churaev [7]
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)

2H⁺ + SO₄²⁻ + 2Na⁺ + 2OH⁻ → 2Na⁺ + SO₄²⁻ + 2H₂O

H⁺ + OH⁻ → H₂O (the net ionic equation)
