The mass of an atom is the sum of massive nuclear particles, protons (as above), and neutrons, neutrally charged, massive nuclear particles. Here the number of neutrons $=$ $120-48=?$

In the neutral element, if there are $48$ positive charges, there are $48$ negative particles, i.e. $48$ electrons, conceived to orbit the massive core.

I could describe the element as $""^120M$, where $Z=48$. What is the name of the element, and what is its symbol?

An element has an atomic number of 76. What is the number of protons and electrons in a neutral atom of the element?

By definition, the , $Z$, is the number of protons, positively charged, massive, nuclear particles, contained in the nucleus. $Z$ specifies the identity of the atom. And if there...

How many protons, electrons, and neutrons does an atom with atomic number 50 and mass number 125 contain?

The tells us how many protons and electrons are in the element. To work out the number of neutrons you do take away atomic number. 125-50 = 75

$"Atom W has 9 protons and 9 neutrons, Atom X has 8 protons and 9"$ $"neutrons. Atom Y has 9 protons, and 9 neutrons. Atom Z has 10 protons"$ $"and 10 neutrons."$ What are the isotopes?

And $Z$ defines the identity of the element: $Z=1,H;Z=2,He;..........Z=6,C;........Z=37, Ru...........$ You don't have to remember these numbers, because a Periodic Table will be supplied to you in every test of...

Sally is making a model of a Mg atom with an atomic mass number of 24. She has balls for the protons, neutrons, and electrons. She has added 6 neutrons to her model. How many more neutrons does she need to add to complete her neutral atom of magnesium?

$Z$, $"the atomic number"$ of magnesium is 12. This means that there are 12 positively charged nuclear particles. This defines the particle as a magnesium atom. To represent the $""^24Mg$...
