How do protons, neutrons, and electrons determine the properties of an atom?

Physics
1 answer:
Naddik [55]3 years ago
7 0

Answer:

Number of protons = Number of electrons

Protons = positively charged atoms

Electrons = negatively charged atom

Neutrons = no charge atoms

The number of protons = electrons because the charge can cancel themselves out

Number of electrons = Determines boiling/ melting point

Lots of electrons = High boiling/ melting point

Low number of electrons = low boiling/ melting point

When antimatter interacts with an equal mass of ordinary matter, both matter and antimatter are converted completely into energy
Ilya [14]

Answer:

  v = 5.88 10⁷ m / s

Explanation:

For this exercise we use the relation

          E = m c²

also indicate that all energy is converted into kinetic energy

          E = K = ½ (M-2m) v²

where m is the mass of antimatter and M is the mass of the ship's mass. Factor two is due to the fact that equal amounts of matter and antimatter must be combined

we substitute  

         m c² = ½ (M-2m) v²

        v² = 2 \frac{m}{M+2m} \ c^2

         

let's calculate

        v = \sqrt{2 \  \frac{4 \ 10^4 }{2 \ 10^6 + 2 \ 4 \ 10^4} \ (3 \ 10^8)^2}

         v = \sqrt{ 34.615 \ 10^{14}}

        v = 5.88 10⁷ m / s
