Group I (alkali metals) and group II (earth-alkali metals)
yes
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
all the elements in group A has the same number of valence electrons
All elements in the same group have the same number of valence electrons.
The elements in Group 1 have one valence electron in their outermost s orbital.
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
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.
All elements in the same A group will have the same number of valence electrons.
all the elements in group A has the same number of valence electrons
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
All elements in the same A group will have the same number of valence electrons.
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
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 group number tells you the number of valence electrons present.
