The number of protons is equally to the usually big number in the element's box. This number will not be a part of a number, it will be a whole number. Hydrogen starts at 1 and then Helium at 2 and so on. Each element is identified by how many protons there are, so the number of protons will change when it is a different element. So the number in the boxes increasing by one each time is the number of protons to directly answer your question.
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
In the atom state (not ionic), yes.
Electrons or Protons. As they are effectively equal in no in a neutral atom.
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
The atomic number or the number of electrons is equal to the number of protons.
No - in fact it is quite rare
In a neutral atom, the number of protons is always equal to the number of electrons.
The number of protons in the nucleus of each atom that has the atomic number.
No
protons and electrons will always be = number
For a chemical element the number of protons is equal to the atomic number.
Atomic number is always equal to the number of protons in an atom.
No
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
In the atom state (not ionic), yes.
#of electrons and # of protons is EQUAL in a neutral atom
yes,,,because the number of protons is equal to the number of electrons. No, when electons are lost or gained by an atom (number of protons stays the same) the atoms become 'ions,' which are positively or negatively charged respectively.
