What element is lightest the elements?
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
What element has one proton and zero neutrons?
Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.
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.
Which of the subatomic particle is the lightest?
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
What is the second lightest chemical element?
From gaseous elements Helium is the 2nd lightest. From solid elements Potassium is the 2nd lightest. From liquid elements Mercury is the 2nd lightest AND heaviest. (only two liquid elements: Bromium is the lightest)
What is the lightest known element with only one proton?
Hydrogen is the lightest element.
What is the lightest element with only one proton?
The lightest element with only one proton is hydrogen.
What is the lightest known element with only one proton called?
That would be hydrogen!!
What element is lightest the elements?
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
Which atom is the lightest?
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
Does isotopes only occur on heavier element?
No - the lightest element Hydrogen has three known isotopes
What does the hydrogen element not have?
hydrogen has only one proton and one electron. it is the lightest element and is a pure element, which means hydrogen is made of one type of atom (in this case hydrogen atoms)
What is the lighest known element with only one proton?
Hydrogen
What is the lightest reactive element?
Hydrogen is not only the lightest element of all, it is also very reactive.
Can hydrogen be broken down by fission?
No. Hydrogen is the simplest and lightest element with the nucleus consisting only of a single proton. There is no smaller nucleus you can make. The only nuclear reaction hydrogen can undergo is fusion into helium.
What element has one proton and zero neutrons?
Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.
Which elements contains only one protron?
Only one element has single proton(proton is correct spelling). The element is Hydrogen. It has a single proton in it's nucleus and no neutrons. A single electron revolves around in s subshell of 1st energy shell( K shell). A Hydrogen atom which has lost it's electron can be said to be proton. No other element known has single proton in the nucleus (protons only reside in nucleus of atom) of it's atom.
