Question

4. “Maximum valence of second period element is four” explain.

Answer 1

Answer:

The maximum covalency in 2nd-period elements is 4

Explanation:

Notice what the "rule" says: the maximum covalency of 2nd-period elements. It doesn't say for all elements in the 2nd period, but rather, when considering each element.

Carbon is the atom that can make four bonds at once, e.g. other hydrocarbons. Not fluorine.

Answer 2

Answer:

The provides statement is true because of the 2p and 2s orbitals.

Explanation:

• There are always 8 in the periodic table.
• 5 are non metals, 2 are metals and one is metallic.
• Out of these combination only 4 electrons permits the atom to gain or loss the weight.
• To losing and gaining requires more power consumption in. Ao, the 2p and 2s are doing this work.
