If no metals can form covalent bond with chlorine I. e they can share electrons with Chlorine then why can't they do the same with Hydrogen? Besides both chlorine and Hydrogen require only one electron

Solution

From next time please give specific examples

Hydrogen can be stabilised both by taking away one electron and giving an electron to it. So when it reacts with the metals, it takes one electron from the metals,like NaH and this is not a covalent bond, it is ionic just like NaCl.

Bonds with metals are always ionic and not covalent, because the metals desperatly require electrons of their own to be stable.

Whenever a non-metallic combines with another non metal, sharing of electron takes place between their atoms and a covalent bond is formed. A covalent bond can also be formed between two atoms of the same non-metal. The shared electrons are counted with both the atoms due to which each atom in the resulting molecule gets an inert gas electron arrangement of 8 electrons (or 2-electrons) in the outermost shell eg : $H_{2}$ molecule.

Draw the electron dot structures for the following molecules.

1. Chlorine 2. Hydrogen chloride

3. Methane 4. Carbon dioxide

5. Ammonia 6. Water

7. Oxygen 8. Ethane

9. Nitrogen 10. Acetylene

Which of the following options correctly represents the bond formed between hydrogen and chlorine in $H C l$ ?

The chlorine atom attracts the bonded pair of electrons in hydrogen chloride. The ability of chlorine to do so can be named as:

Q. Hydrogen combines with chlorine to form HCI. It also combines with sodium to form NaH. If sodium and chlorine also combine with each other, they will do so in the ratio of their masses as:

Q. Carbon forms covalent bonds with itself and other elements such as hydrogen, oxygen, sulphur, nitrogen and chlorine.
