An element cant be the same. That is why they are called elements, but i would have to say wind and air.
No, elements in the same column are in the same family.
elements are in the same group since they react similarly to other elements in that group.
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
Elements in the same group have the same number of valence electrons and hence have similar properties.
Same elements of group have same valency. They possess same chemical behaviour.
All elements in the same group have the same number of valence electrons.
Elements in the same group have the same number of valence electrons.
Yes they are.
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.
They are not. The same
A given compound is always made of the same elements in the same proportion.
Elements in same column belongs to same group. They have same chemical properties.
