I assume you are referring to valence electrons (the "outermost" shell varies widely in the number of electrons it can hold, the valence electrons are a subset of this which are responsible for chemical bonding and reactivity).
The number of valence electrons can only be from 1 electron to 8 electrons, these are divided between the s and p orbitals of a shell (each orbital can hold no more than 2 electrons).
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
The energy levels of an atom hold electrons.
The first energy level of an atom can hold a maximum of 2 electrons. This is due to the arrangement of electrons in orbitals, where the first energy level contains only the 1s orbital. According to the Pauli exclusion principle, each orbital can hold a maximum of 2 electrons with opposite spins.
A sodium atom has an atomic number of 11, meaning it has 11 electrons. The first orbit, or energy level, can hold a maximum of 2 electrons. Therefore, in a sodium atom, the first orbit contains 2 electrons.
An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
The first energy level of an atom can hold a maximum of 2 electrons.
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
In a neon atom, the first energy level or orbit can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons. Therefore, a neon atom would have 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level, totaling 18 electrons.
The energy levels of an atom hold electrons.
The atom will have 3 energy levels. The first energy level can hold up to 2 electrons, the second level can hold up to 8 electrons, and the third level can hold the remaining electron.
The first energy level of an atom can hold a maximum of 2 electrons. This is due to the arrangement of electrons in orbitals, where the first energy level contains only the 1s orbital. According to the Pauli exclusion principle, each orbital can hold a maximum of 2 electrons with opposite spins.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
The 3rd energy level of an atom can hold a maximum of 18 electrons.
A sodium atom has an atomic number of 11, meaning it has 11 electrons. The first orbit, or energy level, can hold a maximum of 2 electrons. Therefore, in a sodium atom, the first orbit contains 2 electrons.
The first energy level of an atom can hold a maximum of 2 electrons. This is due to the principles of quantum mechanics, specifically the Pauli exclusion principle and the shape of atomic orbitals. The first energy level corresponds to the 1s orbital, which can accommodate two electrons with opposite spins.
An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
