Answer:
option D is the correct answer of this question.
ionic compounds lose or gain electrons to become stable.
ionic compounds are bonds between metals and nonmetals.
molecular or covalent compounds share one or more electrons to become stable.
molecular or covalent compounds are bonds between nonmetals.
The answer is PO4^-3 is non-polar.
Explanation:
The charge of a helium atom is zero
It is neutral because
The number of unit negative charges = number of unit positive charges
One unit negative charge = -1.6 x 10^(-19) which is basically the charge of an electron
One unit positive charge = +1.6 x 10^(-19) which is basically the charge of a proton
A helium atom has 2 protons and 2 electrons, so it is neutral
NOTE: an alpha-particle (He2+) is a charged helium atom it has 2 protons and 0 electrons. Charge of an alpha particle = +3.2 x 10^(-19).
