For Fe, its atomic number is 26 and its mass number is 56. How many neutrons does it have?

the number of neutrons available is 30

Explanation:

Given that

The atomic number is 26

And, the mass number is 56

We need to determine the number of neutrons does it have

So, the number of neutrons is

= Mass number - atomic number

= 56 - 26

= 30

Hence, the number of neutrons available is 30

The same would be considered and relevant

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
