Question

explain the properties along the period and group​

Answer 1

Answer:

On the periodic table, elements that have similar properties are in the same groups (vertical). From left to right, the atomic number (z) of the elements increases from one period to the next (horizontal). The groups are numbered at the top of each column and the periods on the left next to each row.

Increases across a period. Decreases down a group. Increases down a group. Decreases across a period until non metals, then increases

Answer 2

Answer:

Generally the automatic radius decreases across a period from lef to right and increase down a given group. the atoms with the largest atomatic radii are located in group and the bottom of the groups. moving from left to right acroos the period electrons are added one at the time to the outer energy shell
