Question

A given atom has 3 protons, 4 neutrons, and 3 electrons. Describe how you can use those three values to describe the structure, charge, and the mass of the atom????????

Answer 1

please?

Answer 2

i will medal!!!

Answer 3

As the number of protons in any element never change (if you change the number of protons of an element it will become a whole different element all together) you can tell what this element is on the periodic table by looking at its no. of protons.

This element has 3 protons, meaning the element is Lithium (Li)

Mass is the number of protons add the number of neutrons so the mass of this element is: 4 + 3 = 7

Charge of an element is dependent on the number of electrons an element has compared to its protons. If an element has more electrons than protons then its charge will be - (negative). This is because electrons are negative and more of them added to an element = more negative charge. However, if an element has less electrons than protons, its charge will be + (positive). This is because protons have a positive charge, and more of them in an element create an overall positive charge. If the no. of protons and electrons are the same, this means the charge is 0 (neutral) because they even each other out.

As this element has an even number of protons and electrons. Its charge is 0 or neutral (whichever you prefer)

And finally, structure of an element depends on its electrons. You need to have done a little work on electron shells/sub-shells and orbitals beforehand. This element has 3 electrons therefore it fills up the 1s sub-shell with 2 of them, and fills up the 2s sub-shell half way with 1 electron. You can draw it like this:

I hope this helps!
