The atomic number tells us the number of electrons and the number of protons., i.e. Atomic Number = Number of electrons = Number of Protons. The Atomic Mass tells the total number of particles in the nucleus, i.e. Atomic Mass = # of protons + number of neutrons. The Group number is the heading at the top of a column in the table. It tells the the outer electron configuration of the atom. This determines many chemical properties of the element.
The group number on the Periodic Table indicates the number of valence electrons an element has. Elements in the same group have similar chemical properties because they have the same number of valence electrons, leading to similar reactivity and bonding characteristics.
Group number represents the group or the family in which the element is present. Based on the group number, the relative reactivity of the element can be known.

What are the vertical columns of a periodic table called?
The vertical columns of a periodic table are called groups or families. They share similar chemical properties because they have the same number of valence electrons.
Elements are organized in the periodic table by their?
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.
What place on the periodic table does radium belong in?
Radium belongs in group 2, period 7 of the periodic table. It is a member of the alkaline earth metals.
When looking at the periodic table of elements that have the same numbers of electrons?
Elements with the same number of electrons have similar chemical properties because they have the same electron configuration in their outer shell. This leads to similar reactivity and bonding behavior among them. Examples include elements in the same group or column of the periodic table.
What group number is fermium in on the periodic table?
Fermium (Fm) is in Group 7 in the Periodic Table.
What is lithium's group number in the periodic table?
The group no. of Lithium is 1 and its period number is 2.
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
