Isotopes have variable numbers of electrons.
true or false
plz

The given statement is false:

Explanation:

Isotopes are those chemical species of same element which contains same number of protons and electrons. But  differ in number of neutrons.

Statement given is false because number of electrons in isotopes of same element remains the same. The difference in the isotopes is due to number of  neutrons present in their respective nuclei.

Hence, given statement is false.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
