As you move across a period in the Periodic Table from left to right, the number of valence electrons increases, typically from one to eight, as elements gain electrons in their outer shell. Conversely, as you move down a group, the number of valence electrons remains the same, but the energy level increases, meaning that the valence electrons are found in higher energy levels further from the nucleus. This results in similar chemical properties within a group, despite differing reactivity and size.
The number of valence electrons increases from left to right across a period.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).

The number of valence electrons in an atom is often related to its position on the periodic table. Elements in the same group have the same number of valence electrons, which influences their chemical properties and reactivity. Valence electrons are the outermost electrons and play a crucial role in bonding with other atoms.
They increase from left to right.
The number of valence electrons increases from left to right across a period.
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.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
The number of valence electrons increases by one as you move from left to right across a period in the periodic table. Sodium (Na) has 1 valence electron, magnesium (Mg) has 2 valence electrons, aluminum (Al) has 3 valence electrons, silicon (Si) has 4 valence electrons, phosphorus (P) has 5 valence electrons, sulfur (S) has 6 valence electrons, chlorine (Cl) has 7 valence electrons, and argon (Ar) has 8 valence electrons.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
The number of valence electrons increases as you go across a period. For example in period 2 the number of valence electrons rises from 1 in Li up to 8 in neon.

Valence electrons are the outermost electrons and play a crucial role in bonding with other atoms.
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).
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
They increase from left to right.
The period number corresponds to the energy level on which the valence electrons are located. As you move across a period from left to right, the number of valence electrons increases by one. This helps determine the reactivity and chemical properties of elements within the same period.
