It is a covalant bond. Because any compound made up of nonmetals will be covalant. Compounds made up of a non metal and metal willl form a ionic compund. :)
The answer is C because the weight is going down so they form a gas.
Answer: A more electronegative atom will have more attraction to the electrons in a chemical bond.
Explanation:
An atom that is able to attract electrons or shared pair of electrons more towards itself is called an electronegative atom.
For example, fluorine is the most electronegative atom.
Due to its high electronegativity it is able to attract an electropositive atom like H towards itself. As a result, both fluorine and hydrogen will acquire stability by sharing of electrons.
Thus, we can conclude that a more electronegative atom will have more attraction to the electrons in a chemical bond.
