Answer:

there are 8 electrons

Explanation:

Calcium is a transition element present in the D block of the periodic table. Calcium has atomic number 20. So its electronic configuration is 2, 8, 8, 2  by the Afbau rule. 2, 8,8 and 2 electrons are present in K,L, M and N shells of the atom. So, we can say that the number of electrons in the third energy level of  a calcium atom are 8.

A(n)is produced around a wire when an electrical current is in the wire.
Nonamiya [84]

Answer: The correct answer is "magnetic field".

Explanation:

A magnetic field is produced around the current carrying wire.

If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic  field around the current carrying wire.

Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.

Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.
