Atom X contains seven protons and seven neutrons. atom Z contains seven protons and eight neutrons. which of the following state
stiks02 [169]

Answer:

The correct answer is option A: they are isotopes.

Explanation:

From atom X we know that the number of protons is 7 and the number of neutrons is 7 and from atom Z we know that the number of protons is 7 and the number of neutrons is 8.

Since the number of protons of atom X and atom Z is the same, we have that atom X and atom Z is the same element. The difference in the number of neutrons tells us that atom X and atom Z are isotopes. Remember that an isotope is one element that has atoms with different numbers of neutrons.            

The mass number is given by:              

A = p + n

Where <em>n</em> is the number of neutrons and <em>p </em>is the number of protons.

For atom X and atom Z we have:

A_{x} = 7 + 7 = 14

A_{z} = 7 + 8 = 15

Hence, they have a different mass number.  

We know that the element with 7 protons is nitrogen. The first isotope is ^{14}_{7}N and the second isotope is ^{15}_{7}N. Both isotopes are stables (they are not radioactive).  

Therefore, the correct answer is option A: they are isotopes.

I hope it helps you!

You split wood with an ax. How would you change the ax to make splitting the wood easier? You would increase mechanical advantag
alex41 [277]
I think you forgot to give the choices along with the question. I am answering the question based on my knowledge and research. You would increase mechanical advantage by <span>making the blade longer from the cutting edge. I hope that this is the answer that has actually come to your desired help.</span>
