Answer: polar molecule.
Explanation:
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.
Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.
Bromine 
is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.
The average atomic mass if the element above is calculated by the sum of the product of the isotope abundance and its atomic mass unit. It is expressed as:
Average atomic mass = Σ xi(Mi)
<span>Average atomic mass = (.7547 x 248.7) + (.2453 x 249.4) = 248.87

Hope this helps.
If you know the Table of elements you can see it on.
Answer:
2Atoms
Explanation:
in 
There exist 2 atoms of nitrogen, 4 atoms of hydrogen and three atoms of oxygen. so the answer is 2atoms
Answer:
Gains
Explanation:
If it gains an electron it causes the atom to become negative since electrons are negative and an overall charge of an atom is neutral. Therefore, it would become negative.
Hope this helps :)
