Is the first electron shell called the L shell?

No, its called the K, then the L is after it and then the M and so on. On the periodic table, the period an element is in is how many electron shells it has.


Is it easier to remove an electron from the outside shell of a K atom than from the outside shell of a Na atom?

Yes, it is easier to remove an electron from the outside shell of a K atom than from the outside shell of a Na atom. This is because potassium (K) is in Group 1 of the periodic table with one valence electron, which is further away from the nucleus compared to sodium's (Na) single valence electron in Group 2. The electron in the outer shell of potassium experiences less attraction to the nucleus, making it easier to remove.


How many electrons are in each shell of hydrogen?

1, because it has an atomic number of one, meaning it has 1 proton & 1 electron. It takes 2 electrons to fill the first electron shell, but hydrogen only has 1. So it remains at the 1st shell.


How many valence electron are in an atom k-42 in the ground state?

An atom of potassium-42 has 19 electrons because potassium (K) has an atomic number of 19. In the ground state, potassium has 1 valence electron because it is located in group 1 of the periodic table.


Why does k shell shields the nucleus the most?

The K shell is closest to the nucleus and has the lowest energy level of all electron shells. Electrons in the K shell experience a stronger electrostatic attraction to the positively charged nucleus, which results in better shielding of the nucleus compared to electrons in higher energy shells.

What is the meaning of K-subshell?

The K-subshell is the first electron shell in an atom, labeled with the letter K. It can hold a maximum of 2 electrons. Subshells further divide into orbitals.

Why k shell have 2 electron in its shells?

k shell has two electrons because in the structure of an atom every shell has an capacity to have fixed number of electrons that why k shell has capacity to have 2 electrons.

Is an electron capture like beta decay?

Yes, when a proton in the nucleus captures an electron from the innermost shell (K shell) it is considered a form of antibeta decay.


What is the first energy level of an electron?
