An ion has a charge of +7. how far is it from being neutral? a. -0.07 b. -7 c. 7 d. 70 e. 0.7

B. -7

Step-by-step explanation:

An atom has a neutral charge with equal numbers of positive and negative particles,

That is, an atom with no chargen or 0 charge is called neutral.

Given,

The ion has a charge of +7,

Also, + 7 - 7 = 0,

Thus, for being neutral the ion needs -7 charge,

Hence, option 'B' is correct.

n

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
