The first electron shell, or energy level only holds 2 electrons. It is the smallest and closest energy level to the atom's nucleus. Hydrogen and helium are the only two elements to have electrons in just the first shell.
there are two electrons the first shell hold
Shell 1: Two electrons Shell 2: Eight electrons Shell 3: Eight electrons Shell 4: Eighteen electrons
A complete valence shell typically holds 8 electrons. However, for elements in the first two rows of the periodic table, the valence shell can hold a maximum of 2 electrons in the first shell and 8 electrons in the second shell.
20 electrons would need 4 shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, the third shell can hold up to 18 electrons, and the fourth shell can hold up to 32 electrons.
The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons.

The first shell in a Bohr model can hold a maximum of 2 electrons.
The first shell (K shell) can hold up to 2 electrons, the second shell (L shell) can hold up to 8 electrons, the third shell (M shell) can hold up to 18 electrons, and the fourth shell (N shell) can hold up to 32 electrons.
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.

The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
A complete valence shell typically holds 8 electrons. However, for elements in the first two rows of the periodic table, the valence shell can hold a maximum of 2 electrons in the first shell and 8 electrons in the second shell.
20 electrons would need 4 shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, the third shell can hold up to 18 electrons, and the fourth shell can hold up to 32 electrons.
The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
The first shell of an atom can hold a maximum of 2 electrons.
