Yes it is different. Ion contain more protons.
Ion.
You have an ion with a positive or negative charge. Ex.: [H+] is a positive hydrogen ion waiting to accept another atom to form a compound with.
no
Positive ion
It will be Nb2+ or Niobium(II) ion, as the atomic number of niobium is 41. (Note: Initially molybdenum was given as the answer. But the atomic number of Mo is 42 and not 42).
A positive ion is a type of atom with less electrons than usual. A proton is a subatomic particle that makes up atoms.
A proton has a positive electric charge.
An ion. If electrons are in excess over proton then it is negative ion. And if less then positive ion
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
Because it is a proton. A hydrogen atom is a proton and an electron; if you take the electron away to form a positive ion, all that's left is the proton.
This partice is called atomic nucleus.
An Ion. An ion can have an overall positive or negative charge. The negative charge of an electron exactly cancels the positive charge of a proton, so when an atom has an equal number of both, it carries zero charge. An ion with more protons than electrons has a positive charge, and is more specifically termed a cation. An ion that has more electrons than protons, and therefore a negative overall charge, is called an anion.
A single proton (not part of a larger nucleus) is the same as a positive hydrogen ion.
An ion may have either a positive charge or a negative charge. So there term "positive ion" simply tells which of the two general types it belongs to.
A proton has the same electrical charge as a singly ionized positive ion.
neutron is neutral, proton is positive electron is negative
That may be a proton, a positive ion, or any of a host of other particles.
