What statement about models of isotopes below is accurate?

Chemistry
1 answer:
ryzh [129]3 years ago
4 0

Answer : The correct option is (C) each picture represents an isotope of lithium because they each have 3 protons.

Explanation :

Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.

As in the given picture, the number of protons are same but number of neutrons are different.

As we know that atomic number is either equal to number of protons or electrons for neutral atom.

The number of protons in the given picture are 3.

So, the element will be lithium with atomic number 3 and all are the isotopes of lithium.

Hence, the correct option is (C) each picture represents an isotope of lithium because they each have 3 protons.

The pka of hf is 3.2 determine the pkb of hf?
Julli [10]

Well, first we must remember that

pK_{a}+pK_{b}=14

This is because

K_{a}*K_{b}=10^{-14}

-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14

So then

pK_{b}=14-pK_{a}=14-3.2=1.8
