An atom of beryllium (be) has 4 protons. it has a net charge of 0. how many electrons does it have? 1 2 4 8

4

Explanation:

Net worth means it has to be -4. Electrons have a negative charge, so 4 electrons is equivalent to -4.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

since electrons are negative the answer is neagtaive
