Question

Answer the following questions about phosphorus (atomic symbol: P)

A) The Group number is

B) The number of valence electrons is

C) To acquire an octet of electrons requires it to (gain/lose #) electrons

D) The net charge of a phosphorus ion is

E)The complete symbol for the phosphorous ion is

Fill in the blanks in the following statements.

Ions with a positive charge are called _____. Ions with a negative charge are called ____.

In ionic compounds, metals have a ____ charge and non-metals have a ____ charge.

Answer 1

P = 15 1s²2s²2p⁶3s²3p³

A) The Group number is VA

B) The number of valence electrons is 5

C) To acquire an octet of electrons requires it to (gain/lose #) electrons gain 3 electrons

phosporous gain three electrons to get stable octet elctrons argon

P +3e^- -----> P^-3

15e^-               18e^-

D) The net charge of a phosphorus ion is (P^-3 ) -3

E)The complete symbol for the phosphorous ion is P^-3

Fill in the blanks in the following statements.

Ions with a positive charge are called _cation____. Ions with a negative charge are called _anion___.

In ionic compounds, metals have a _positive___ charge and non-metals have a _negative___ charge.
