Answer:
Atoms only share electrons in covalent bonds. covalent bonds are only formed between nonmetals. there are two different types of covalent bonds; polar and nonpolar. in a polar covalent bonds electrons are shared unequally because one atom has a stronger force of attraction than the other (EX. H2O). In a nonpolar covalent bond, the electrons are shared equally because they're electronegativity is also equal (EX. Cl2).
Overall, the atoms electronegativity determines the way it shares electrons
C₆H₆ + 3H₂ → C₆H₁₂
Benzene + 3 molecules of hydrogen = cyclohexane
So essentially what happens is that benzene contains three double bonds and when reacted with hydrogen then these three double bonds can be broken and the hydrogen bond to the tetravalent carbon to restore its for bonds forming cyclohexane
Mass and distance.
Hope this helps:)
Answer: B) metals, non-metals, metalloids
An example of a metal is iron. A non-metal example is oxygen, which is a gas at STP (standard temperature and pressure).
A metalloid is a bit of a mix between a metal and non-metal element. It's sorta like an element that has both properties of metals and non-metals, or it's in a murky gray area. An example of a metalloid would be silicon.
