Answer:
Neither accurate nor precise
Explanation:
The values were not near or even the same as the accepted value thus making it neither accurate nor precise.
Answer:
1A: ns^1
2A: ns^2
5A: ns^2np^3
7A: ns^2np^5
Explanation:
<u>According to IUPAC, the columns 1A, 2A, 5A, and 7A correspond to the groups, 1, 2, 15 and 17, respectively</u>.
The outer electron configuration of these columns are the following:
Column Outer electron configuration
1A ns^1
2A ns^2
5A ns^2np^3
7A ns^2np^5
Therefore, for the column 1A the s orbital has only one electron, for the column 2A has the s orbital completed with 2 electrons, for the column 5A the number of electrons in the s orbital is complete (2) and the number of electrons in the p orbital is 3, for the column 7A the s orbital has 2 electrons and the p orbital has 5 electrons.
