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.
Argon is in the third period of the modern periodic table.
On the Periodic Table of Elements, gold is listed on the 6th period in the 11th group.
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
a row going acrossNOT to be confused with groups or families which go down in columns and have to do with valence electrons
The ionization energy graph doesn't grow at a constant rate because the energy required to remove an electron from an atom depends on factors such as the size of the atom, the number of electron shells, and the shielding effect of inner electrons. As you move across a period on the periodic table, the increasing nuclear charge leads to higher ionization energies, but there are also periodic fluctuations due to electron configuration changes.
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.

A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.

Across a period, as we move from left to right, the electronegativity increases in the periodic table.
The electro-negativity of elements increases as you move across a period.
