denis-greek [22]3 years ago
5 0

Answer:

Atomic number of copper is 29. The atomic number of an atom is determined by the number of protons in the nucleus. Therefore, there are 29 protons in an atom of copper. In a neutral atom, there are equal number of protons and electrons. Therefore, there are 29 electrons in a copper atom. Mass number of copper is 64.

Number of protons + Number of neutrons = mass number.

Therefore, number of neutrons = 63 -29 = 35

If gas particles start colliding with the walls of their metallic container with increased force, what is their direct effect?.
aliya0001 [1]
<span>So we want to know what is the direct effect of the gas particles if the force of their collision with the walls of the container is increased. Pressure, microscopically, is defined as the number of collisions per unit area. If we increase the force of the collision, the pressure increases so that is the direct effect. </span>
