All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
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.
All elements in the same A group will have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
The elements in a group have the similar chemical properties dueto presence of same no of electrons in their outermost shell but they differ physically because physical properties are related to their atomic sizes from top to bottom in a group atomic size increases so their physical properties also differ.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
The Actinoids group contain all the synthetic elements. All the elements that have an atomic weight of 95 and above do not occur naturally. They are part of the actinoid elemental group.
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
all of them are really
Outer or valence electrons
