A covalent bond is likely to be formed between two elements which
1 Have similar electronegativities
2 Have low ionization energies
3 Have low melting points
4 Form ions with a small charge
Explanation:
A covalent bond is possible between Similar and Dissimilar atoms. Two atoms with same electronegativity or similar electronegativity can form a covalent bond. For example, \(2 H\) atoms combine to form a covalent bond in hydrogen molecule. Also, one \(C\) atom combines with \(4 H\) atoms to form four \(C - H\) covalent bonds in methane.

The bond between two identical non-metal atoms has a pair of electrons
1 Unequally shared between the two
2 Transferred fully from one atom to another
3 With identical spins
4 Equally shared between them
Explanation:
Bonds between identical, non-metals, are purely covalent due to the same electronegativities of the bonded atoms. Hence, the bonded atoms have a equal hold on the shared pair of electrons, e.g. : \(F _2, O _2, N _2\)

Which of the following substances has covalent bonding
1 Germanium
2 Sodium chloride
3 Solid neon
4 Copper
Explanation:
Germanium substance has covalent bonding Germanium and silicon are both semiconductors. They are neither conductors nor insulators. This we can study in principles of electronics.

The covalency of nitrogen in \(HN{O_3}\) is
1 \(0\)
2 \(3\)
3 \(4\)
4 \(5\)
Explanation:
(d) \(( + 1) + x + 3( - 2) = 0 \Rightarrow 1 + x - 6 = 0\)\( \Rightarrow x = 6 - 1 = 5\).
