The formation of an ionic bond involves a number of different processes. in the formation of sodium chloride, represented by the equation given below, two steps result in a release of energy. choose those two steps. (yes, you fill in two bubbles on your scantron for this question. you must choose both correct answers to receive credit for the question.) 2na(s) + cl2(g) → 2nacl(s) a. attraction of na+ and cl– to form nacl. b. removal of an electron from na. c. the addition of an electron to each cl atom d. conversion of na(s) to na(g). e. dissociation of cl2 to form 2 cl atoms.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
