Answer:
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.

germanium (Ge)
Explanation:
both belong to the same group
Answer:
When those traits change over time through many generations in response to changes in environmental conditions, scientists call that process adaptation. In the example of beetle color above, the yellow color trait supported successful survival and reproduction in the new environment.
Answer:
Ca^2+
Explanation:
As we know, more energy is required to remove an electron from a positively charged ion than is required to remove an electron from a neutral atom. Hence, the second ionization energy of calcium is greater than its first ionization energy.
However, the third and fourth ionization energies of calcium are much higher than the second ionization energy because they involve removal of electrons from an inner filed shell. This process requires a lot of energy and is often not feasible.
Hence, the most common ion of calcium must be Ca^2+ where only two electrons are removed from calcium.
Answer:
True. If they're talking about the first orbital around the nucleus then yes, its true. The element will be unstable and die
