Choose the option from the drop-down menus that is best described by each statement. involves combining of nuclei: produces dangerous radioactive waste: have high activation energies: releases large amounts of energy: occurs in the stars: drives chemical plants:

Explanation:

Hello,

In this case, to state each option, one must recall what nuclear fusion and nuclear fission are. At first, in nuclear fusion two smaller atoms are combined to make one larger atom of a different element, gathering the neutrons, electrons and protons of the involved elements. However, in nuclear fission, larger atoms of certain elements are split into two smaller atoms of different elements.

In such a way, the combining of a nuclei accounts for nuclear fusion, the producing of dangerous waste applies for nuclear fission due to the splitting, the high activation energies are present nuclear fusion since it is energetically harder to combine than to split, both of them releases large amounts of energy since the energy contained into the splitting or combining particles is storaged into a tiny space (the atom), just the nuclear fusion occurs in the stars to power them and just the fission is driven in chemical plants to produce energy.

Best regards.

Trust me dawg

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
