Question

what is the sequence to label the subshells in an atom​

Answer 1

Answer:

For atoms, the notation consists of a sequence of atomic subshell labels (e.g. for phosphorus the sequence 1s, 2s, 2p, 3s, 3p) with the number of electrons assigned to each subshell placed as a superscript. For example, hydrogen has one electron in the s-orbital of the first shell, so its configuration is written 1s1.

Answer 2

Answer:

The sequence to label the subshells in an atom is s,p,d,f.

Explanation:

• Physicists and chemists use typical notation to indicate the electron configuration of atoms and molecules.
• For atoms, the notation is the specified sequence of atomic subshells (for example, for phosphorus, sequences 1s, 2s, 2p, 3s, 3p), and the number of electrons assigned to each subshell is indicated by superscripts.
• For example, hydrogen has one electron in the s orbital of the primary shell, so its composition is described as 1s1.
• Now consider two electrons, as in the case of lithium. Lithium's 1s subshell has two electrons, one in the (high energy) 2s subshell, so its configuration is described as 1s22s1.
• The electron configuration can be recognized by the fact that the core electrons are the same as the inert gas of the previous period and are therefore valence electrons.
• During the period, each element depends only on some previous subshells. In certain configurations, the orbital write order is not completely fixed, as only orbital occupancy has physical implications.
• For example, the electron configuration in the titanium state is often described as either [Ar] 4s23d2 or [Ar] 3d24s2.
