How to read this
- A row (period) is the number of electron shells. Elements in period 3 carry three of them.
- A column (group) tells you how many electrons sit in the outer shell — which is why a group behaves alike.
- Atomic weight runs at roughly twice the atomic number: about as many neutrons as protons.
- The 28 lanthanides and actinides are drawn below the table. Slotting them in would stretch it to 32 columns.
Frequently asked questions
Q. What are Vanadium's number and symbol?
Element 23, symbol V, atomic weight 50.942.
Q. Where does it sit in the table?
Period 4, group 5 — a transition metal.
Q. What is its electron configuration?
1s2 2s2 2p6 3s2 3p6 4s2 3d3, or [Ar] 4s2 3d3 for short.
Q. How many neutrons does it have?
Rounding the atomic weight and subtracting the atomic number gives 28. The exact count depends on the isotope.
