actually it never changes as in 16 the group all the elements have 4 valence electrons in outermost shell so they can neither accept nor lose the electns
The metals have tendency to lose electrons. The elements of group-1,2 and 13 have tendency to form cations.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
the vertical column is called group in the periodic table.
halogens or group 17
The metals have tendency to lose electrons. The elements of group-1,2 and 13 have tendency to form cations.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Metals give electrons.
Fluorine is the most electronegative element in the periodic table of elements. Electronegativity is a measure of the tendency of an atom or functional group to attract electrons towards itself.
group 17, halogens
Group 16 elements.
the vertical column is called group in the periodic table.
group 18, noble gases
halogens or group 17
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
