What is the total number of orbitals in the valence shell of an atom?

Answer 1

valence electron are the electrons in the atoms outer most orbit making themselves avalible for bonding and different chemical interactions. a quick check to figure out how many valence electrons are present is to look at a Periodic Table, pick and element and elemental positions back to group one (excluding the transition metals. for example, N has 5 valence electrons carbon has 4 F has 7

note: when we say N has a valence of 3 its because 2 of the valence electrons are found in a pair leaving 3 electrons available for bonding. so N has 5 valence electrons and a "valence" of 3

Answer 2

The total number of orbitals present in the valence shell differs with every atom.

It is because the valence shell is the outermost shell for any atom.

It differs with the atomic number of the atom.

For example:-

1. Hydrogen has only one electron in 1s subshell which has only one orbital.

Therefore, it is the valence shell for hydrogen.

2. Oxygen has 8 electrons and for it the valence shell is L-shell which has two subshells i.e. 2s and 2p which together have 4 orbitals.

Therefore, the no. of orbitals varies with atomic number and isn't same for every atom

Answer 3

The total number of orbitals in the valence shell of an atom is dependent on the sublevel or type of orbital. For example, in the s sublevel, there is only one orbital; in the p sublevel, there are three orbitals; in the d sublevel, there are five orbitals; and in the f sublevel, there are seven orbitals.

Answer 4

Depending upon the element, there are from 1 to 8 valence electrons. Hydrogen has 1, helium has 2, oxygen has 6, argon has 8, etc.
