Complete the paragraph below by choosing the correct term from the drop-down menu as you complete the information about the periodic table of elements so we have questions the circle column labeled with one it’s called a what is it a family group shell. Or row second question there are 18 or 17 or nine or seven groups families on the periodic table of elements, and the same group on the periodic table are similar because they have the same number would be protons, neutrons, nuclei or valence electrons next this also means that they have similar what it be properties size or colors and then we had the circle label to. It’s called a column. Group or family Next there are there are 1718 nine or seven. On the table elements in the same period are similar because that has the same number of protons, energy levels, neutrons or electrons or electrons shells.

Answer 1

Complete the paragraph below by choosing the correct term from the drop-down menu as you complete the information about the periodic table of elements:

So we have questions. The circle column labeled with one is called a group. There are 18 groups on the periodic table of elements, and the same group on the periodic table are similar because they have the same number of valence electrons. Next, this also means that they have similar properties. The circle labeled with two is called a period. There are 7 periods on the table. Elements in the same period are similar because they have the same number of energy levels.
