B I think is right. Hope this helps!
Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
Answer: an organic base, a phosphate group, and a sugar
Explanation:
A nucleotide is made up of 3 parts. We know a nucleotide is not made up of water so we are left with 2 choices. Nucleotides are made up of phosphate group, 5-carbon sugar, and nitrogenous base. The nitrogeneous base is typically adenine. The answer choice that matches this the closest is an organic base, a phosphate group, and a sugar.
The organic base is the nitrogeneous base and the sugar is the 5-carbon sugar.
