Number of protons = the atomic number of the element
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
An atom of iron has 26 protons. An atom of oxygen has 8 protons. The atoms are significantly different.
Protons, they have a positive charge.
Mass number/Atomic Mass
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
atomic mass number - protons = number or neutrons
The protons are in the center of a atom.
Atoms are electrically neutral. If the protons and electrons were unequal, there would be an overall charge. That would give an ion, not an atom.
Yes, the number of electrons in an atom is equal to its atomic number. The atomic number is the number of protons in the nucleus of an atom, and since atoms are electrically neutral, they have the same number of electrons.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
protons and neutrons
There are 18 protons in an Aragon atom.
