Elements in the same group have the same number of valence electrons and hence have similar properties.
GROUPS have more in common than PERIODS. I don't know why, I just know the answer.From, Bryan Hollick
The groups have equal number of valence electrons. The elements in same groups have same chemical properties.
Groups. Elements in the same group have similar electronegativity properties.
yes, families and groups the same meaning in the periodic table.
What they have in common in groups is that they have the same stupidest
They are called groups and have similar properties with the other elements in that group.
They are called groups...
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
All groups have the same number of valence electrons and hence have similar properties.
The elements in vertical group are called families because the elements possess same characteristics.
elements in a group have the same number of valence electrons.
