They do not differ in any way, except they are the 1 to 8 electrons in the highest energy ground state orbitals of that atom.
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
I believe there are 3 electrons
Electrons can produce light when they are "excited," and jump outside their ground state, then hop back, releasing a photon of light.
energy is given out. this is emitted in the form light ie each atom has its own characteristic emission spectra.
An alkaline element in the ground state typically has 1 or 2 electrons in its valence shell. This is because alkaline elements belong to group 1 or 2 of the periodic table, which corresponds to 1 or 2 valence electrons.
Carbon has four valence at ground state has group four element
The Noble gas group all have 8 valence electrons.
The total number of valence electrons in Boron's ground state is 2
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
An atom of aluminum in the ground state has 3 electrons in its valence shell. Aluminum has an electron configuration of 2-8-3, so its valence shell is the third shell, where the last 3 electrons reside.
A fluorine atom in the ground state has 7 valence electrons.
Atom Mg-26 in the ground state has 2 valence electrons. Magnesium (Mg) has an atomic number of 12, so it has 12 electrons in total. In the ground state, the electron configuration is [Ne] 3s2, which means it has 2 electrons in the outermost shell (valence electrons).
This shows 19 electrons, with 4s1 as a valence electron. This is potassium (K).
8 valence electrons (so do all of the other noble gases)
No. Germanium in the ground state has 32 electrons, 4 of these are valence electrons which can participate in chemical reactions. Perhaps that is where you are getting confused.
