How many atoms of group one would react with one atom of group five?
PSYCHO15rus [73]
Group 1 elements are comprised of: (1) hydrogen, sodium, lithium, potassium, rubidium, caesium, and francium. The tendency of these atoms is to lose one of their electrons such that they become charge +1. 

Group 5 elements contains the vanadium, niobium, tantalum, and dubnium. It is quite hard to predict the oxidation number of these elements such that it will be hard to determine the number of atoms needed to react with them. Their valence electron is 5, and they react by losing them. Hence, in order to reach the octet rule, 3 group 1 elements should be reacted.

11. Which of the following best describes the range of
Gnoma [55]

Answer:

D. All real numbers

Step-by-step explanation:

The range of a function is all of the possible x-values (which is easiest to understand if you can view a graph), and the domain of a function is all possible y-values.

So, you could put any x-value into this function (and it would have a corresponding y-value)

The domain [y] is limited, but the range [x] is best described as all real numbers

(if it's hard to remember which is which, d comes before r alphabetically, and x comes before y alphabetically)
