There is no clear pattern. At room temperature (293 K), hydrogen on the left of the table is a gas, as are elements in group 18, plus one or two in each of groups 15-17.

By 1615 K, amongst the elements up to uranium, all the elements in group 1, groups 12, 16, 17 and 18 and several in group 15 have reached their boiling points but none in groups 13 and 14. From groups 2 to 11, only magnesium (group 2) has reached its boiling point.

What do you notice about the boiling points as you move from left to right across the periodic table?

The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.

What do you notice about the number of valence electrons as you move from left to right across a periodic table example Na-Ar?

The number of valence electrons increases by one as you move from left to right across a period on the periodic table example Na to Ar. This is because the number of protons increases across the period, leading to an increase in the number of electrons in the outermost energy level.
