hydrogen
26 nuetrons, 22 electrons, and 22 protons
Magnesium is the element that has 12 neutrons in it.
The chemical element of chlorine has 18 nuetrons,17 protons and 17 electrons
it has 35 nuetrons, 30 protons, and 30 electrons with a mass of 65
quark
no it has a nutral charge because in the middle of protons and electrons there is nuetrons. nuetrons have a nutral charge and so does the atom.
This is 100% dependant on the element and the isotope of the element. Not every nucleus is the same.
Iodine
Calcium (Ca)
Is called an Isotope.
An element has a small case in the center called the nucleus. Inside the nucleus contains protons an nuetrons. Protons have a positive charge and nuetrons have a negative charge. On the outside and are energy levels that have electrons and are negatively charged
