Correct answer is:
<h2>The maximum number of orbits in an atom is <u>Seven.</u></h2><h3>Explanation:</h3>
Every energy level has a limited one orbital including two electrons. The orbits are settled in the sub-levels and there can be further than 1 sub-level as the number of energy levels rises. On energy level 1, there is 1 sub-level and 1 orbital. Energy level 2 can possess 2 sub-levels and 2 orbitals. These remain to develop as you progress from the nucleus of the atom, closing up with an infinite potential number of levels and orbits.

Explanation:
Answer:

Explanation:
Given:
- mass of nerf projectile,

- velocity of nerf projectile,

- mass of the gun,

Now in this case the collision can be assumed to be perfectly elastic.
<u>For an elastic collision:</u>

where:
recoil velocity of the gun
