The half life of a scandium-46 is 84 days. The scandium-46<span> is used in oil refining as a tracer to monitor the oil movement and it emits </span><span>extremely high energetic gamma/beta radiation. So the half-life of the radioisotope scandium-46 is 84 days. The </span>Scandium 46 created by neutron activation, is a synthetic isotope of Scandium.
vocational or technical education programs.
Explanation:
A vocational or technical education program is one that awards certificate that can help in securing jobs.
In a vocational or technical program, one is studying for a specific job role. It involves and hands on practical processes within a short period of time possible that makes one viable for some roles.

<span>Begin by classifying which energy level, and indirectly principal quantum number, n, resembles to the N shell.
no. of orbitals =n2
In your case, the fourth energy level will contain
n=4⇒no. of orbitals= 4^2=16
The number of subshells is given by the principal quantum number.
no. of subshells=n
In your case, the fourth energy level will have
no. of subshells = 4 this is the answer
to check:
the fourth energy shell will can hold a thoroughgoing of no. of electrons=2⋅42=32 e−</span>
