Answer:
10. D
9. A
8. A or B
Explanation:
10. Calcium has 20 electrons, but the Calcium ion has 18 electrons.
9. The mass of electrons are negligible.
8. Electrons have a very small mass where some consider it to have no mass.
I. Because they're a limited resource
2 Because they're a cause of carbon pollution.
<span>According to the law of conservation of mass, the masses of the products and reactants must be the same. Adding calcium to the product side is considered a mistake if it is not in the reactant side of a particular chemical equation because it is impossible to produce calcium from thin air (unless this is a nuclear reaction).</span>
The Ionic Bond formation for Lithium Oxide. Lithium is in group 1 of the periodic table. A lithium atom will lose 1 electron to form a stable 1+ ion. An oxygen atom will gain 2 electrons to form a stable 2- ion.
