There are 1000
Ne has three p-orbitals.
There is only one 2s orbital in an atom.
24
A neutral Si atom has 3 valence electrons, which reside in the 3rd energy level valence shell. Therefore, there are 3 valence orbitals in a neutral Si atom.
There are a total of three p orbitals for an atom with principal quantum number n = 2: px, py, and pz. These orbitals are oriented along the x, y, and z axes.

17. The electronic configuration of bromine is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 4p5
A neutral bromine atom has 35 electrons.
A ground state atom of bromine has 28 core electrons. This can be determined by subtracting the number of valence electrons in a neutral bromine atom (7) from the total number of electrons in a bromine atom (35).
the answer is 3
1s22s22p6

Ne has three p-orbitals.
There are 9 occupied orbitals in a phosphorus atom's ground state: one 1s orbital, one 2s orbital, three 2p orbitals, one 3s orbital, and three 3p orbitals.
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5. Each separated letter in that notation represents a distinct electron orbital. Therefore, there are 5 electron orbitals in chlorine.
The second shell in an atom contains 4 orbitals and can hold up to 8 electrons.
