A neutral nitrogen atom has 7 electrons, 7 protons, and 7 neutrons. What is its total charge? If we remove 2 of the electrons, now what is its charge? what is its charge if we add 2 electrons to the neutrol atom instead? give charge in Coloumbs.
neutral atom q=0;
if you remove 2 electrons:
q= +2•1.6•10⁻¹⁹= +3.2•10⁻¹⁹ C
if you add to electrons:
q= - 2•1.6•10⁻¹⁹= - 3.2•10⁻¹⁹ C

To determine the total charge of an atom, you need to consider the number of electrons and protons. Electrons carry a negative charge, while protons carry a positive charge. Neutrons, on the other hand, are electrically neutral and have no charge.
In the case of a neutral nitrogen atom with 7 electrons and 7 protons, the total charge is zero. The negative charge of the 7 electrons is exactly balanced by the positive charge of the 7 protons, resulting in no overall charge.
If we remove 2 of the electrons from the neutral nitrogen atom, we would have 5 electrons remaining. The number of protons (7) remains the same. Since electrons are negatively charged, by removing 2, the atom's total charge would become positive. Specifically, +2 electrons are removed, resulting in 5 (-) charged electrons and 7 (+) charged protons. Therefore, the charge would be +2e, where e represents the elementary charge of -1.6 x 10^-19 Coulombs.
On the other hand, if we add 2 electrons to the neutral nitrogen atom, we would have 9 electrons in total (7 original + 2 added). The number of protons (7) remains the same. Since electrons are negatively charged, by adding 2, the atom's total charge would become negative. Specifically, +2 electrons are added, resulting in 9 (-) charged electrons and 7 (+) charged protons. Therefore, the charge would be -2e, where e represents the elementary charge of -1.6 x 10^-19 Coulombs.
