Scandium. Its atomic number is 21. It is the first d block element.
Carbon is a none metal element. atomic number of it is 6.
Calcium is a metal element. atomic number of it is 20.
Uranium is a radioactive element. It is in the f block. We use it for make energy.
Fluorine has the smallest atomic radius of all the p-block elements. This is because as you move across a period from left to right, the atomic radius decreases due to increasing nuclear charge pulling the electrons closer to the nucleus.
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

The atomic number of the element that belongs to the s-block in the periodic table is 2.
An atom is the smallest building block of matter that retains the characteristics of that matter.
Silicone is a none metal element. atomic number of it is 14.
Carbon is a none metal element. atomic number of it is 6.
Calcium is a metal element. atomic number of it is 20.
Palladium is a d block metal element. atomic number of it is 46.
Uranium is a radioactive element. It is in the f block. We use it for make energy.
Boron, atomic number 5, is a Group 13 element, in Period 2, in block p.
Fluorine has the smallest atomic radius of all the p-block elements. This is because as you move across a period from left to right, the atomic radius decreases due to increasing nuclear charge pulling the electrons closer to the nucleus.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.
The element with electron configuration 1s22s23p1 is phosphorus, which has an atomic number of 15.
