No, the former answer (striked through below this) is very wrong!
Hydrogen (elemental H atom) contains only 1 (one!) electron (1s1) and since a H ion (H+) has lost that one to become stable, this H+ ion has no (zero!) electrons at all.
Only the very rare and exceptional, negatively charged hydride ion H- ion contains two electrons (1s2 configuration, not favoured, not enough electronegativity)
Yes. A Hydrogen atom "wants" to be stable, so it gains an electron to be iso-electronic with helium. After that, its electron configuration is 1s2. H+

An atom that has lost or gained electrons is an?
an ion
How many electrons in scandium ion?
Scandium typically has 21 electrons in a neutral atom. In an Sc3+ ion, it loses 3 electrons, so the ion would have 18 electrons.
How many valence electrons does S2- have?
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
How many electrons are present in 40Ca2?
A calcium ion with a 2+ charge (Ca2+) has lost two electrons. A neutral calcium atom (Ca) has 20 electrons, so Ca2+ would have 18 electrons.
What ion has 53 protons and 54 electrons?
The ion would be Iodine (I). It has 53 protons and normally has 53 electrons, so if it gains an extra electron, it becomes a negatively charged ion with 54 electrons.
How many electrons does an H plus ion have in the first shell?
The H+ ion has no electrons.
How many electrons are in an Mg2 plus ion?
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
How hydride ion and helium atom have same number of electron?
Both the hydride ion (H-) and helium atom have two electrons. The hydride ion gains an extra electron to achieve an electron configuration similar to helium (1s²), making them both have two electrons overall. Helium naturally has two electrons in its electron configuration.
How many valence electrons will hydrogen have after chlorine steals electrons?
The hydrogen ion H+ is without electrons.
Which ion has no electrons?
All elements have electrons, when the amount of electrons they have changes they are called ions. They only element that forms an ion with no electrons is Hydrogen (H). To learn more about electrons and ions you should inquire about electron configuration.
What is the chemical formula for hydrogen ion?
HTeO4- is the formula for hydrogen tellurate ion.
How many protons electrons and neutrons are present in a hydrogen ion?
Hydrogen is a funny critter. It always has one proton, and it usually has no neutrons. But rarely it can have one neutron, and even more rarely, it can have two neutrons. There is more. Hydrogen can appear either as just the proton having loaned out its electron to become a positive ion (H+), or it can at times borrow an electron and become a negative ion (H-). That means the ion might have two electrons, but usually it has no electrons.
What is the number of protons and electrons in a sulfide ion -2?
A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.
How many unpaired electrons are in a Co2 plus ion?
In a Co2+ ion, cobalt has two fewer electrons than its neutral state, so it loses two electrons. Cobalt in its neutral state has 7 unpaired electrons. Upon losing two electrons, the Co2+ ion has 5 unpaired electrons.
How many electrons and protons does an ion have?
There are many different types of ions, having many different quantities of electrons and protons. The H+ ion has one proton and no electrons. That's the simplest.
Why is o6 a helium like ion?
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
How many protons and electrons in Be2 plus ION?
Beryllium (Be) has 4 protons and 4 electrons in its neutral state. When it forms the Be2+ ion, it loses two electrons, leaving it with 4 protons and 2 electrons. The Be2+ ion has a 2+ charge because it has lost two negatively charged electrons.
