The valence electrons.
When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not likely to react.
Helium will not react with carbon as helium is chemically inert.
check valence electron
describe the type of electron configuration that makes a atom stable and not likely to react
Because charge only reveals the number of valence electrons of an atom while the identity of an atom also relies on the number of non-valence electrons.
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
What type of atom or molecule is in lamppost
Elements are made from one type of atom.
You can determine what element an atom is by it's amount of sub-atomic particles and their positions. Every element has a different amount of electrons, so that is the easiest way to determine what type an atom is. If you wanted to determine it more broadly, for example, which group an element was in, you could just count the amount of electrons in the outer shell, as each group is unique in this way.
The protons don't change because if the number of protons changes, the type of element the atom is changes. The number of protons determine the species of the atom.
Thermoreceptors react to variation in temperature.
By definition, an element is a substance with only one type of atom. So no, each element has its own type of atom.
