Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.

What element has 1 proton and 2 neutrons?
An element with 1 proton is hydrogen. An Isotope called Tritium has one Proton and two Neutrons. Hope this helps.
What is the only element that has no neutrons inside the atom?
There is no ELEMENT which contains no neutrons HOWEVER there is an isotope of hydrogen called protium which is a single proton surrounded by a single electron.
Why is hydrogen the 1st element?
It has the lowest atomic number (one) as its nucleus contains only one proton (and (usually) no neutrons).
What element has one proton one electron and no neutrons?
Yes, every element of matter has a corresponding element of antimatter, and antimatter elements have nuclei consisting of antiprotons, not protons. It depends, however, on whether one considers antimatter elements to be elements or "anti-elements."
What is the metalloid element with the fewest number of protons?
If you look at the periodic table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.
What have one proton and no neutrons in its nucleus?
The only element that has one proton and no neutrons is a hydrogen atom.
What element has 1 proton and 2 neutrons?
An element with 1 proton is hydrogen. An Isotope called Tritium has one Proton and two Neutrons. Hope this helps.
What is the only element that has no neutrons inside the atom?
There is no ELEMENT which contains no neutrons HOWEVER there is an isotope of hydrogen called protium which is a single proton surrounded by a single electron.
How many electrons protons and nuetrons are in hydrogen?
One Proton One electron zero neutrons
What is the most abdundant element?
The most abundant element is Hydrogen (H). It is also the simplest element with one Proton, one Electron, and no Neutrons.
An atom of hydrogen is made up of?
All isotopes of hydrogen contain one proton. The single thing that makes each element unique is the number of protons in its nucleus. Only that. Neutron count can vary with different isotopes of an element, and electron count can vary as we see an atom loan or borrow electrons. Proton count always identifies an element, and nothing else. The word "isotope" means the same element, with the same properties, but with different numbers of neutrons. Most hydrogen atoms have one proton and no neutrons. Deuterium is the isotope that has one proton and one neutron, and tritium has one proton and two neutrons.Hydrogen with oxygen forms water; deuterium and oxygen forms "heavy water". Tritium is radioactive, and decays into helium-3.
An isotope differs from regular atoms of an element by having a different number of?
Neutrons. As an example, hydrogen has three isotopes, Hydrogen, Duterium and Tritium. Hydrogen atoms consist of one proton and one electron. Duterium atoms consist of one proton, one electron and one neutron. Tritium atoms consist of one proton, one electron and two neutrons.
How many negatives positives and neutrals do a hydrogen atom have?
A hydrogen atom has one proton, one electron, and zero neutrons.
Why is hydrogen the 1st element?
It has the lowest atomic number (one) as its nucleus contains only one proton (and (usually) no neutrons).
Is only one kind of atom in a element?
Yes and no. All elements are composed of the same basic "stuff"--- protons, neutrons and electrons. But when the number of protons, neutrons and electrons change, a completely different element appears. A given element will always have the same number of protons but can have several numbers of neutrons. Substances with identical numbers of protons but different numbers of neutrons are called isotopes. Take for example hydrogen. One proton bound in an atom with no neutrons is what we know as protium, the most abundant isotope of hydrogen. One proton bound in an atom with one neutron is called deuterium while one proton bound in an atom with two neutrons is called tritium. These are all isotopes of hydrogen because they contain only one proton, but differ in the their number of neutrons.
How man protons does an element have to have to make it radioactive?
One proton is in tritium, a radioactive isotope of hydrogen with two neutrons.
What element has one proton one electron and no neutrons?
Yes, every element of matter has a corresponding element of antimatter, and antimatter elements have nuclei consisting of antiprotons, not protons. It depends, however, on whether one considers antimatter elements to be elements or "anti-elements."
