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.
answer: 6.4
work:
Solve the problem.
Let's start by solving the numerator,
(5 + 3)² <em>step one: add 5 + 3 </em>
(8)² <em>step two: simplify 8²</em>
64
now, let's simplify our denominator
1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>
1 + 32 - 23 <em>step two: add 1 + 32.</em>
33 - 23 <em>step three: subtract 33 - 23</em>
10.
now, put the numerator back over the denominator.
64/10
let's simplify by dividing, we get 6.4.

Answer:
15/20 and 18/20
Step-by-step explanation:
Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10
multiples of 4: 4, 8, 12, 16, 20
multiples of 10: 10, 20
Least common denominator = 20
Rewrite fractions: 15/20 and 18/20
Answer:
14
Step-by-step explanation:
Its like a clock, except directly away from the six is not twelve, it's 13. That means the clock would have to have added two numbers for there to be a whole number facing the six.
