1) Between calcium ion and magnesium ion, which one is the largest and why? a) calcium ion because it has one more shell than magnesium ion

b) magnesium ion because it has fewer electrons than calcium

c) calcium ion because it lost a larger density of electrons

d) magnesium ion because it has one more shell than calcium ion

2) Between phosphide ion and sulfide ion, which is the smallest and why?

a) sulfide ion because it gained fewer electrons

b) phosphide ion because it gained more electrons

c) sulfide ion because it lost fewer electrons

d) phosphide ion because it lost more electrons

explanation:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
