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.
In the atom state (not ionic), yes.
Number of protons is always equal to the atomic number of an element. Example-at.no. Of hydrogen is one so it has one proton
Electrons or Protons. As they are effectively equal in no in a neutral atom.
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
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 atomic number reflects the charge number of the nucleus. It is always equal to the number of protons found in the nucleus.
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
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
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.
In the atom state (not ionic), yes.
