A hydrogen ion, often called a proton, because that's all it is - one proton in the nucleus and no electrons. Tiny, but powerful!

The common ion charge of some elements in the periodic table is zero what does that tell you about the element?
That it does not gain or loose electrons.
What is the number of electrons in fluorine ion?
If the ion is the most common anion of fluorine, a fluoride ion, it contains 10 electrons.
What do an ion of Ca2 plus and an atom of Ar have in common?
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
What is the charge in a phosphorus ion gaining or losing electrons?
Common valences are 5 or 3.
What is the charge of an ion that gained electrons?
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
The common ion charge of some elements in the periodic table is zero what does that tell you about the element?
That it does not gain or loose electrons.
How many unpaired electrons are there in an oxide ion?
they're are zero unpaired electrons.
What is the number of electrons in fluorine ion?
If the ion is the most common anion of fluorine, a fluoride ion, it contains 10 electrons.
What is the charge of an ion having Y protons and Y electrons?
It has zero charge.
How many unpaired electrons does the ion contain Tl?
The number of unpaired electrons in Tl-81 ion is zero, this in case of ejection of one electron from Tl-81 atom. Thx!!
What does a fluoride ion have in common with a neon and a sodium ion?
Both fluoride ion and sodium ion are isoelectronic with neon. That means all have 10 electrons.
Why deos an ion have an electrical charge?
Because an ion has either more or less electrons than in neutral form, when the number of electrons equals the number of protons. So the net charge (total '-' and '+' is not zero)
What do an ion of Ca2 plus and an atom of Ar have in common?
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
An atom that has lost or gained electrons is an?
an ion
What is the charge in a phosphorus ion gaining or losing electrons?
Common valences are 5 or 3.
When an atom has different amounts of protons and electrons it is called an?
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.
What is the charge of an ion that gained electrons?
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
