As we descend down the group, the atomic radii increases. This is because the number of shells increases.

Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
What do all elements in a group have?
Atomic mass
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
Do elements in the same group have the same atomic mass?
No.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
What happens to the atomic size of the elements as on goes from the top to the bottom of a group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What happens to the group 1 elements as you go down the table?
As you go down group 1, the atomic number and atomic mass increase. Electronegtivity decreases and atomic radius increases.
What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it

What do all elements in a group have?
Atomic mass
How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
What are atomic numbers of the elements in group 13?
5,13,31,49,81,113
Do elements in the same group have the same atomic mass?
No.
Do elements in the same group have similar atomic numbers?
No. Elements in the same group have same number of valence electrons.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
