They are the same
Elements that have the same number of valence electrons will have similar chemical properties, binding with other elements in the same way and same proportions.
they have the same energy levels
the share similar charasterisitics
they are all formed from the same elements
GROUPS have more in common than PERIODS. I don't know why, I just know the answer.From, Bryan Hollick
Same elements of group have same valency. They possess same chemical behaviour.
What they have in common in groups is that they have the same stupidest
They are the same
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
they are all formed from the same elements
Elements that have the same number of valence electrons will have similar chemical properties, binding with other elements in the same way and same proportions.
The elements in same column have equal number of valence electrons. They have similar chemical properties.
they have the elements and they are in the same substances
they have the same energy levels
the share similar charasterisitics
Elements in the same family (or group) have the number of valence electrons in common. Ex: Family 16 - 6 valence electrons.properties
