Question

How many electrons are in a sodium atom?

  1. 11
  2. 22
  3. 33
  4. 12

hintHint:

In a neutral atom number of protons and electrons are equal.

The correct answer is: 11


    • In a neutral atom number of protons and electrons are equal.
    • Atomic number = number of protons.
    • Atomic number of sodium is 11, as number of electron is same as number of proton hence number of electron in sodium is 11.

    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.
