How can you tell the difference between a period and a group?
Groups tell you how many electron shells the element has and periods have the same number of electrons in the outermost shell.
There is no difference.
Periods tell you how many electron shells the element has and groups have the same number of electrons in the outermost shell.
Periods and groups can be reversed.
How are the categories on the periodic table organized?
By the size of the atom.
By the properties of the element.
By the negative charge from each element.
By the positive charge from each element.
