What is the trend of boiling point ang melting point when the atomic number is increases?

Answer 1

As atomic number increases, boiling point/K increases due to there being more electrons, which create a larger strength of negative charge around the nucleus of the atom. This affects the van der waals' forces (the forces of attraction between molecules or atoms), and they become stronger. With stronger forces, it requires more energy input to change the state of the element - resulting in a higher boiling/melting point. [:

Answer 2

There is not a positive correlation or linear relationship between increasing atomic number and density. Internuclear forces create spacing, or density losses. Second, elemental density is based on #atoms/volume, and Atomic Mass/volume so the this relationship is not direct.

Answer 3

There are about three trends that affect the melting and the boiling point. The three trends includes the strength of the inter-molecular forces, the number of carbon atoms, and the type of bond.

Answer 4

The boiling point increases as the atomic number of the halogens increases. This can be explained with London dispersion forces becoming more evident due to a the larger amount of polarized electrons.

Answer 5

Generally, as the atomic number increases, both the boiling point and melting point of elements tend to increase. This is due to an increase in the strength of intermolecular forces as the atomic number increases, leading to a higher energy requirement to overcome these forces in order to change the state of matter.

Answer 6

as atomic number increases, the B.P increases as well [:

Answer 7

temperature will increases
