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).
What else can I help you with?
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
What does t he energy levels of an atom hold?
The energy levels of an atom hold electrons.
How many electrons does the first energy level lf an atom have?
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.
How many electrons are In the first orbit of a sodium atom?
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.
How many energy levels are in an atoms of Mg?
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 how many electrons?
The first energy level of an atom can hold a maximum of 2 electrons.
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
What does t he energy levels of an atom hold?
The energy levels of an atom hold electrons.
How many electrons are there in each orbit of a neon atom?
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.
If an atom has 11 electrons how many energy levels will it have?
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.
How many electrons in the first energy level of lithium?
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 how many electrons?
The 3rd energy level of an atom can hold a maximum of 18 electrons.
How many energy levels are in an atoms of Mg?
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.
How many energy levels are occupied in an atom of oxygen?
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.
How many electrons can an atom's third energy level hold?
The third energy level of an atom can hold eight electrons.
What is the number of electrons that can occupy the first shell of an atom?
The first shell of an atom can hold a maximum of 2 electrons.
How many energy levels are found in an atom of carbon?
There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
