Ionization and electronegativity are related to the periodic table in that: a. both increase going across a row and up a column. b. both decrease going across a row and increase going down a column. c. electronegativity increases going across a row and up a column while ionization energy decreases. d. there is no relation.

The answer would be A.

Explanation:

c.

explanation:

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.
