An atom has 9 electrons and 9 protons at the start . if it loses 2 electrons, the net charge on the atom will be ? if the atom instead gains 4 electrons the net charge will be ?

Answer : If it loses 2 electrons, the net charge on the atom will be (+2) and If it gains 4 electrons, the net charge on the atom will be (-4).

Explanation :

We are given:

Number of electron in an atom = 9

Number of protons in an atom = 9

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.

When an atom gains electrons, it will form a negative ion known as anion.

According to the question,

When the atom loses 2 electrons then the net charge on the atom will be (+2) because it will form a positive ion by losing electrons.

When the atom gains 4 electrons then the net charge on the atom will be (-4) because it will form a negative ion by gains electrons.

i think so it’s will be b yes i believe its

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
