True. Its a matter of the number of electrons in the outer shell. Elements in the same group have the same number.
Electronegativity decrease down in a group.
No the most reactive metals are in the first group on the periodic table. They get more reactive as you go down a group
A period are the rows going across on a periodic table, a group is the rows going up and down. there is no relation in them.
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
It tends to increaseThe atomic radius increases down the group
In fact it increases down the group because ionization energy decreases down the group
it goes up and down
Atomic radius increases down a group. Metallic character also increases down the group.
Electronegativity decrease down in a group.
Each column going down the periodic table is an atomic group.
As we move down a group, electronegativity decreases.
from above to down negetivity decreeses
A period are the rows going across on a periodic table, a group is the rows going up and down. there is no relation in them.

Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
Down the group, size increases. Because number of shells increases.
