How many protons neutrons and electrons are there in a neutral atom of 43k (potassium-43)?
Veronika [31]

Answer:

             Number of Protons  =  19

             Number of Neutrons  =  25

             Number of Electrons  =  19

Explanation:

Number of Protons:

                               The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Potassium is 19 therefore, it contains 19 protons.

Number Neutrons:

                             The number of neutrons present in atom are calculated as,

                               # of Neutrons  =  Atomic Mass - # of protons

As given,

                                Atomic Mass  =  43

                                # of Protons  =  19

So,

                                # of Neutrons  =  43 - 19

                                # of Neutrons  =  24

Number of Electrons:

                                   As we know for a neutral atom the number of electrons are exactly equal to the number of protons present in its nucleus. So, for 19 protons in neutral Potassium atom there must be 19 electrons.

Why are gamma rays not affected by a magnet as they pass over it?
Assoli18 [71]
Gamma is not affected by both fields because it isnt charged. 

Only alpha and beta ray will be affected because they are charged with positive and negative ions respectively.

In otherwords, <span>Gamma rays are high-energy photons of light, which have zero electric charge. So they are not affected by magnetic fields</span>

Here's a chart. .

If that doesnt help tell me :)
