I am Vanadium transition metal.
The periodic table is arranged in groups and periods. The elements in each group are chemically similar.
The groups are vertical while the periods are horizontal.
Period 4 opens with the transition metal potassium having 19 protons. If the transition metal in question has four more protons than the alkali metal found in period 4, 19 + 4 = 23.
This means that the transition metal has 23 protons and this corresponds to Vanadium.
