I think the number of protons in the nucleus the number of valence electrons atomic mass...
Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
Answer:
homogenous is a uniform and consistent mixture ; heterogenous is a mixture that is non-uniform
Explanation:
usually if you can separate the mixture/particles it is heterogenous. For example, pizza is heterogenous because you can separate the dough from the tomato sauce from the cheese. vinegar is homogenous (cannot separate mixture)
