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.
Better labeling so I can understand.
Idont under stand this thanks
Good morning,
Answer:
1.678 rounded to the nearest hundredth is 1.68
Step-by-step explanation:
By looking at the number 1.678 it’s clear that the hundredth digit is 7
since 8∈{5,6,7,8,9} then we delete the 8 and add one to 7
we get 1.68 .
:)
Answer:
300 times bigger.
Step-by-step explanation:
That would be (1.8 * 10^27 ) / (6 * 10^24)
= 0.3 * (10^27/10^24)
= 0.3 * 10^3
= 3 * 10^2
= 300.
