Hey....I need help with my homework.

I'm in 9th grade, high school.
Its pyhsical science about Atomic Math..
Heres the question:

Multiply the atomic number of hydrogen by the number of electrons in mercury, which has an atomic number of 80.

1 x 80 = 80

Sure, I can help you with that question. To find the answer, we need to first understand what the atomic number represents and how to calculate the number of electrons in an atom.

The atomic number of an element tells us the number of protons in its nucleus. In the case of hydrogen, the atomic number is 1 because it has one proton in its nucleus.

To calculate the number of electrons in an atom, we can use the fact that atoms are electrically neutral, meaning they have an equal number of protons and electrons. So, for hydrogen, since it has one proton, it also has one electron.

Now, let's apply this knowledge to the given question. We are asked to multiply the atomic number of hydrogen (1) by the number of electrons in mercury (which has an atomic number of 80).

To find the number of electrons in mercury, we can again use the fact that atoms are neutral. So, an atom of mercury with an atomic number of 80 will have 80 protons and thus 80 electrons.

Therefore, to find the answer, we can multiply the atomic number of hydrogen (1) by the number of electrons in mercury (80):

1 * 80 = 80

So, the answer is 80.

Remember, the key here is to understand the concept of atomic number and how it relates to the number of protons and electrons in an atom.
