Question
What is the name of this element?
- Lithium
- Boron
- Carbon
- Neon
Hint:
Atomic number = number of protons
The correct answer is: Neon
- Atomic number = number of protons and atomic mass = number of protons + number of neutrons.
- In the given model there are 10n and 10p. Hence, atomic number of the element is 10 and the element is Neon.
- Atomic mass of the element is 20.

How many shells are present in potassium?
The region surrounding a nucleus, known as an electron shell, is where electrons are typically located.
¶1s, 2s, 2p, 3s, 3d, 4p, 5s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, and 8s are the numbers in order. Although it is difficult to remember, there is a simple approach. Move from top to bottom, top right end to the bottom left of each line, in the order of the lines.
¶The lowest accessible shell nearest to the nucleus must be occupied by electrons.
¶The most electrons that can fit into each shell are:
¶There were two in the first shell, eight in the next, and eight in the last.
The twenty-first element, calcium, has two more electrons in the fourth shell.
