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 period is argon in?
Argon is in the third period of the modern periodic table.
What is gold's period?
On the Periodic Table of Elements, gold is listed on the 6th period in the 11th group.
What is a period in a periodic table?
a row going acrossNOT to be confused with groups or families which go down in columns and have to do with valence electrons
The elements with the smallest atomic radii are found in the?
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
What is a real world ex of a periodic motion?
Earth, in which "the period of Earth's orbit is one year, and its frequency is one orbit per year." - Encyclopedia Britannica Online
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 as you move from left to right across the period in the periodic table?
it increases
A row across the periodic table is called a?
groupsi
A row of elements across the periodic table is an?
The rows across the periodic table are called periods.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
What is the row across the periodic table called?
Period
What decreases across the periodic table?
Atomic size decreases across a period
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.
How does Electronegativity trend across the periodic table?
Electronegativity increases across a period (left to right).
What are patterns in the periodic table?
These are the patterns of the periodic table across the period. 1. The atomic radius reduces as we move across a period from left to right, 2. The ionization energy increases as we move across a period. 3. The electron affinity decreases as we move across a period. Learning them enables us to have a clear view of elements in the periodic table.
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
