They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
The element on the right has one more proton =]=]
they have same valence electrons. their properties are periodic in nature.
Transition elements are the D block on the periodic table. They are between Magnesium and Aluminum and below.
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
The difference in atomic number between adjacent elements is always one (1).
On the left of the periodic table, especially group 1 and group 2 elements.
They all are Halozen elements.
Transition elements are the D block on the periodic table. They are between Magnesium and Aluminum and below.
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
The periodic table comprises of metals (on the left) ,non-metals(on the right ) and transition elements (between metals and non-metals) in the periodic table.
Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.
Metals are located on left side in periodic table.Eg-group 1,2 elements
Representive elements
The difference in atomic number between adjacent elements is always one (1).
On the left of the periodic table, especially group 1 and group 2 elements.
Elements with similar physical and chemical properties are located in a group.
They all are Halozen elements.
On the right side of the periodic table.
Nonmetals.
