When forming ions, all metals have a (+) positive charge. Which of the following BEST explains why?
(a.) Metals are known to add protons to their nuceili and become
positively charged.
b. All metals tend to lose one or more valence electrons giving them a
positive charge.
c. All metals gain electrons giving them a positive charge.
d. Metals are known to lose protons and gain neutrons resulting in a
positive charge.

i believe it is a.) released into

explanation:

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

∠gdh and ∠edh on edg.

answer is c
