Question

The number of valence electrons in an atom with electronic configuration 1s2 2s2 2p6 3s2 3p3

Answer 1

Answer:

3

Explanation:

1s2,2s2,2p6,3s2,3p3 is phosphorus having 3

Answer 2

Answer:

The number of valance electrons are $3$.

Explanation:

• A chemical bond is formed by the valance electrons, which are the number of electrons in an atom's outermost shell.

• The atom with an electronic configuration $1s^22s^22p^63s^23p^3$ has $3$ valence electrons in the outermost shell.

• An atomic orbital with two orbital lobes and an orbital node at the nucleus is called a p orbital.

• Only six electrons can fit inside a single p subshell.
