All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
Elements with the same number of valence electrons are found in the same group or column of the periodic table. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron.
Same elements of group have same valency. They possess same chemical behaviour.
All elements in a group have same chemical properties. They have same number of valence electrons.
Elements that have the same number of valence electrons are found in the same group of the periodic table. For example, all elements in Group 1 (e.g. H, Li, Na) have 1 valence electron, while elements in Group 18 (e.g. He, Ne, Ar) have 8 valence electrons. Valence electrons determine an element's chemical properties and reactivity.
All elements in the same A group will have the same number of valence electrons.
Elements with the same number of valence electrons are located in the same group on the periodic table. For example, elements in Group 1 (e.g., hydrogen, lithium, sodium) all have 1 valence electron, while elements in Group 17 (e.g., fluorine, chlorine, iodine) all have 7 valence electrons.
All elements in the same group have the same number of valence electrons.
Outer or valence electrons
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
Seven elements are found in group A or group 1.These are Hydrogen,Lithium,Sodium,Potassium,Rubidium,Caesium and Francium. Except Hydrogen all are metals.
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
