In an element: yes
Ions vary, like Ca+2 has two less electrons than protons.
Yes, surely the same + and - charge
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
Yes, most atoms do have more electrons than protons. This is because atoms are electrically neutral, and the number of protons (positive charge) in the nucleus is balanced by the number of electrons (negative charge) surrounding the nucleus.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
Two atoms that have the same number of protons are called isotopes.
Proton Number
Atomic Number
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
An element by definition refers to all atoms with the same number of protons; so any atom with 1 proton is the same element as all other atoms with one proton; which would be helium. And then, all atoms with 2 protons would be the same element; hydrogen. But the atoms that have 1 proton and the atoms that have 2 protons cannot be the same element.An ion is an element with a different amount of electrons, where if it is a positive ion it is missing an election compared to a "normal" element and if it is a negative ion it would have an extra election compared to a "normal" element.An isotope is a member of the same element but it has a different number of neutrons.
The number of protons.
Protons and electrons
False. In a neutral atom, the number of electrons is equal to the number of protons. This balance between positively charged protons and negatively charged electrons is what keeps the atom electrically neutral.
