<span>The smallest unit of an element that retains all the characteristics of that element is called an A. atom.
Atoms consist of protons, electrons, and neutrons, but they are particles and don't have the characteristics of the element which is why D is incorrect. B and C are not the smallest units - atoms are smaller than them.
</span>
I believe that the answer is D.
I hope this helps. :)
The metalloids are on the right side of the periodic table B, Si, Ge, As, Sb, Te, and At. The nonmetals are also on the right side next to the metalloids, there should be a He at the top right of the periodic table and there should be one more nonmetal at the top left of the periodic table that is H. And from the metals they are all on the middle next to the metalloids, starting from Li, Be, Na, and Mg as so on all of those are metals.
C. both sources of energy rely on water.
Explanation:
Hydroelectricity and tidal energy are similar energy sources because they both rely on water.
They harness the power of moving water to produce their energy.
- Tidal energy is the energy derived from moving water as crashing waves in an ocean.
- Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
- They are both renewable energy sources.
