<h3><u>Answer;</u></h3>

a. atomic mass of ~ 12 amu

b. atomic number of 6

e. 6 protons, 6 neutrons

f. valence of 4

<h3><u>Explanation</u>;</h3>
  • Carbon is a chemical element in the periodic table. <em><u>Its symbol is C.</u></em>
  • <em><u>Carbon has an atomic number of 6</u></em>, atomic number is the number of protons in the nucleus of an atom, therefore <em><u>carbon has 6 protons, </u></em>and since the number of electrons are equal to the number of protons in a neutral atom, then <em><u>the number of electrons in carbon atom is 6.</u></em>
  • Carbon requires to gain or loose 4 electrons to attain a stable electronic configuration and therefore<em> </em><em><u>it has a valency of 4.</u></em>
  • <em><u>The atomic mass of carbon is ≈ 12 a.m.u</u></em>. Carbon is found in group 14 of the periodic table.

Doss [256]
Borders are still guarded zealously and fought for - via wars when required and when not required in equal measure. I see nations fighting
 over water  that preciously scarce resource of the future. I see that terrorists still abound - the Osama Bin Laden types still roam the Earth terrorizing countries and peoples with newer weapons and newer methods of instilling terror. I see that the United States is no longer the sole superpower of the world -- the most powerful country on Earth. I see the most powerful countries dominating the world as being China, India, Brazil and Russia in that order. I see that China and India have become the equivalent of the US and the erstwhile Soviet Union - fighting another Cold War between them and competing for resources and influence around the world.
