The electrical charge of an atom having 15 proton, 14 neutrons and 16 electrons is -1. The correct option is D.
What is an atom?
An atom is the smallest unit of any matter which comprises of central nucleus and electrons revolving around the nucleus in definite energy shells. The atom is made up of protons, neutrons and electrons.
The electrical charge of an atom can be calculated as,
Charge of an atom = number of protons - number of electrons
Charge = 15 - 16 = -1.
The neutrons are neutral and do not contribute to the charge, the protons are positively charged and electrons are negatively charged in an atom.
Therefore, the charge of an atom with 15 protons, 14 neutrons and 16 electrons is -1. The correct answer is option D.

I cant entirely tell for now but an article on rodioactivity should solve the problem
Answer:
Protons
Explanation:
The atomic number represents the number of protons. Therefore, as the atomic number increases, the number of protons does too.
I hope this helps! :)
Answer:
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
