What is the maximum number of electrons that can be accommodated in the K shell of an atom? Correct Answer 2

The correct answer is 2.

Key Points

• The K shell of an atom can hold 2 electrons.
• The "K" shell is closest to the nucleus, whereas the "Q" shell is the furthest away.
• Those "n" values are also known as energy levels for simple atoms since they usually correspond to the row number on the periodic table.
• The second description examines how electrons behave within the shells.
• An electron shell is an orbit that electrons follow around an atom's nucleus.

Additional Information

• Each orbit can hold a maximum of 2n2 electrons, where n is number of orbit.
• The electronic configuration of an element gives the distribution of electrons in each of the orbits.

The electronic configuration of an element(Bohr-bury Rules):

• The electrons in an atom arranged by certain rules known as Bohr-bury rules.
• The electrons revolved in fixed orbit around the nucleus of an atom.
• The orbits are numbered from the center outward. The first orbit closest to the nucleus numbered as 1 and named it as K - shell, next is numbered as 2 and denoted as L - shell, the next with 3 as M - shell, 4 as N - shell and so on.
• The maximum number of electrons in the outermost shell cannot be exceed 8 and in the second last shell 18, irrespective of the shell number.
