no
A = mass number = sum of p+ and n0 Z = atomic number = no. of p+ An alpha particle consists of two protons and two neutrons, so if an one were to be emitted from a radioactive atom, the atomic number (Z) would be reduced by two, and the mass number (A) would be reduced by four.

Proton.
The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level. For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.

Yes, you could possibly reduce load sheeding if you take time to cut back on energy loss. You can encourage your customers to cut back during peak demand times.
no
2.5 as a reduced mixed number is 21/2
becasue congressmen is REDUCED
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.
4 can not be reduced because it is a whole number.
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
Yes.
