The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.

Wiki User
∙ 7y agothe difference is that they are different types of metals, and group one is highly reactive and generally soft. Group two however is less reactive and is also harder.

∙ 11y agoGroup 1: metals, highly reactive, don't exist in nature by themselves.
Group 18: gases, non-reactive, exist in nature in small amounts.

What is the difference in reactivity between elements in family 1 and elements in family 18?
group 18
What are the two names for group 18 elements?
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
What are elements main features?
The main group elements are groups 1, 2, and 13 - 18.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
What is the name for group 1 and 18 on the periodic table?
What is the difference in reactivity between elements in family 1 and elements in family 18?
group 18
What are in the main group of elements?
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
What are representatave elements?
The representative, or main group elements are the elements in groups 1, 2, and 13 - 18.
What is special about group one a eighteen on the periodic table?
Group 1 elements are alkali metals. Group-18 elements are inert in nature.
What are the two names for group 18 elements?
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
What are elements main features?
The main group elements are groups 1, 2, and 13 - 18.
What are elements in Groups 1 and 2 and in Groups 13-18?
Group 1- Alkali metals Group 2- Alkali earth metals Group 3-12_Transition metals Group 17-Halogens Group 18-Noble gases
How does the number of valence electrons for elements across a period?

Which of the elements are representative elements in the periodic table?
All of them. "Representative elements" means "representative of the group". A group which doesn't have any representative elements would be a largely meaningless group.Group-1, 2,13-18 include representative elements. Group-1 and 2 contain metals. Group 13-17 contain non metals. Group18 comprises of noble gases.
