Atoms increase in size as you go down a column and are larger going from right to left across a row.
because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increases ,,
it increases as you go down the periodic table
Down a group, the atomic radius increases as the number of shells or energy levels increases.
It tends to increaseThe atomic radius increases down the group
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
Atomic Mass
it increases as you go down the periodic table
Down a group, the atomic radius increases as the number of shells or energy levels increases.
It tends to increaseThe atomic radius increases down the group
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
the larger the highest energy level number, the larger the atomic radius (Apex)
Each column going down the periodic table is an atomic group.
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
The larger the highest energy level, the larger the atomic radius.
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
atomic radius increases down a group as the number of shells increases
The density properties generally change as you go down the columns of the Periodic Table by increasing.
