Most titanium atoms have 22 electrons. Are there some titanium atoms that have a different number of electrons?
All titanium atoms have
The thing to remember about electrons is that a neutral atom will always have a fixed number of electrons surrounding its nucleus.
That number of electrons is given by the number of protons present inside the nucleus. In order for an atom to be neutral, the number of protons it has inside its nucleus must be equal to the number of electrons that surround the nucleus.
Consequently, every atom of titanium must have
So, if an atom of titanium has a different number fo electrons, then said atom is actually an ion, meaning that it carries a net charge.
For example, titanium can lose four electrons to form the titanium(IV) cation,
So, to sum this up, an atom of titanium must have
Keep in mind that the number of neutrons located inside the nucleus can vary between various atoms of titanium, i.e. between isotopes.
