Group members in the Periodic Table indicate the number of valence electrons an atom has, which directly influences its chemical behavior. Elements in the same group share similar properties because they have the same number of valence electrons, affecting their reactivity and bonding patterns. For example, group 1 elements have one valence electron and are highly reactive, while group 18 elements have a full set of valence electrons, making them largely inert. Understanding these group trends helps predict how an atom will interact with others based on its valence electron configuration.
Valence electrons determine the reactivity of the element.
The valence is determined experimentally.
the number of valence electrons determine the reactivity of the atoms
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
To determine the number of valence electrons in SiCl3Br, we need to account for the valence electrons of each atom in the molecule. Silicon (Si) has 4 valence electrons, each chlorine (Cl) atom has 7 valence electrons, and bromine (Br) has 7 valence electrons. Therefore, the total is 4 (Si) + 3 × 7 (Cl) + 7 (Br) = 4 + 21 + 7 = 32 valence electrons.
To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.

its Atomic Mass.
They determine how great is the valence of a chemical element; they are the electrons involved in the formation of a chemical bond.
the number of valence electrons determine the reactivity of the atoms
To determine the number of valence electrons from an electron configuration, look at the highest energy level (n value) of the electrons in the configuration. The number of electrons in this highest energy level is the number of valence electrons.
To determine the number of valence electrons in an atom, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
