When moving left to right across a period on the Periodic Table, the number of valence electrons increases by one with each element. This is because the atomic number increases, resulting in a higher number of electrons in the outermost shell (valence shell).
Electrons in the outermost shell are valence electrons!
The number of valence electrons remains the same as you move across a row on the periodic table. For example, in row 2 (elements from Li to Ne), all elements have 2 valence electrons. However, the chemical reactivity of these valence electrons can change as you move across the row due to the increasing nuclear charge affecting their interactions with other atoms.
Gallium (Ga) has 3 valence electrons.
There are 3 valence electrons in an atom of aluminium.
Indium has 3 valence electrons.

Valence electrons
the electrons in the outermost shell of an atom are considered to be the valence electrons.
The number of valence electrons remains the same as you move across a row on the periodic table. For example, in row 2 (elements from Li to Ne), all elements have 2 valence electrons. However, the chemical reactivity of these valence electrons can change as you move across the row due to the increasing nuclear charge affecting their interactions with other atoms.
Gallium (Ga) has 3 valence electrons.
There are 3 valence electrons in an atom of aluminium.
Indium has 3 valence electrons.
No, krypton has 8 valence electrons.
The beryllium atom has 4 electrons and the valence is 2.
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
