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.
The answer is B. It is a relation and also a function at the same time because it satisfies a specific domain
It is impossible to list the set of rational numbers using the roster method because the set of rational numbers is uncountable/inumerable.
There is no way to list all the members of the set of rational numbers.
Idk what it means, sorry and good luck
If I’m correct it should be 7 because range is least greatest subtracted from most greatest and the problem is asking from the green box so 67-60=7
