Electrons orbiting an atomic nucleus do not do so like planets round the sun, they do so in shells round the nucleus.
Each electron shell can accommodate 2n2 electrons, i.e. the first shell can accommodate 2 electrons, the second shell 8 electrons, the third shell 18 electrons, etc.
Electrons always fill the smallest shells (nearest the nucleus) first as this is the lowest energy configuration.
The shells do not have to be full - for instance a hydrogen atom has just one electron and thus the first shell has only one electron in it not two.
It is possible to push an inner electron up into a higher shell (by providing energy) if there is a vacancy - however it will fall back and when it does so it will emit a photon of light this is why things glow when they get hot.
What else can I help you with?
How many electrons can occupy a single molecular orbital?
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
How many electrons can occupy each shell in an atom?
The number of electrons that can occupy each shell in an atom is determined by the formula 2n2, where n is the shell number.
How many electrons per orbit can be found in an atom?
The number of electrons per orbit in an atom is determined by the energy level of the orbit. Each orbit can hold a maximum number of electrons, with the first orbit holding up to 2 electrons, the second holding up to 8 electrons, the third holding up to 18 electrons, and so on.
How many electrons does carbon have on its second shell?
Carbon has 4 electrons on its second shell. This is calculated based on the maximum number of electrons that can occupy the second shell, which is 8.
How many electrons are in the outermost orbit of neon?
Neon has 8 electrons in its outermost orbit. The outermost orbit, also known as the valence shell, can hold a maximum of 8 electrons. Neon is a noble gas and has a full valence shell, making it stable and unreactive.
How many electrons can occupy a single molecular orbital?
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
How many electrons are in the second orbit of sodium?
The second orbit has 8 electrons.
How many electrons orbit nitrogens nucleus?
Nitrogen has 7 electrons orbiting its nucleus in a neutral state. Two electrons occupy the first shell, while the remaining five electrons are distributed in the second shell.
How many electrons can occupy the 2s subshell and 3d subshell?
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
How many electrons are in the third orbit of manganese?
13 electrons are in the third orbit of Manganese.
How many orbitals do the electrons of Beryllium occupy?
The electrons in beryllium occupy a total of four orbitals. Beryllium has 4 electrons, which fill the 1s, 2s, and 2p orbitals.
How many electrons occupy the second orbital?
8
How many electrons in each orbit ring for lead?
