The first electron energy level can only hold 2 electrons. Hydrogen only has 1 first energy level electron as it only contains one proton and one electron total.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
nuetron and electron
no , it only emits energy if it moves from a higher energy level to a lower energy level.
An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
no
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
level one electron contain more energy
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
nuetron and electron
when it is on the very outside level away from the nucleusA valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)It is an electron in the outermost shell of the atom.
no , it only emits energy if it moves from a higher energy level to a lower energy level.
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
It has a negative charge.
An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
An atom in which an electron has moved up to a higher level is in an excited state. The lowest state of the atom is called the ground state.Ê
