Correct answer is <span>Fuels do not have to be purchased to generate power.</span>
Answer:
fluoride ion with a charge of -1
Explanation:
If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
Ionization energy increases from left to right because the left wants to lose elctrons and the right wants to gain electron
As you go a group it is easier lose lose because the electrons are farther away from the nucleus and there is less attraction from the positive charges.
It should be 3p3. the p level can hold 6 electrons
Rubidium group 1, 1 valence electrons very reactive
Mg2,2 very reactive
Al 3, 3 reactive
