What is the charge of an ion with p=9 n=10 e=10 ?

Explanation:

The element fluorine has 9 protons and 9 electrons. In the image on the right it has gained an electron and now has 10. Since it has 10 negative particles, but only 9 positive ones, its net charge is –1. A negatively charged ion is called an anion.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
