What else can I help you with?
How many protons does an atom of the first element listed on the periodic table have?
Hydrogen, being the first element, has one proton and one neutron in its nucleus.
Which element does not have any neutron in this atom?
Hydrogen is the only element without any 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 element has 1 proton 1 neutron and 1 electron?
The element is hydrogen and the isotope is tritium (1H3)
What element has an mass number of 2 and 1 neutron?
This is the isotope of hydrogen - deuterium.
What element has 1 neutron and mass number of 2?
This is the isotope of hydrogen - deuterium.
What is the element which do not posses neutron in its nucleus?
There is an isotope of hydrogen called 'protium', which only has 1 proton and 1 electron, with no neutron.
What is an example of an atom without a neutron?
The only element that does not have a neutron in its nucleus is hydrogen-1, which consists of one proton and one electron.
What is in hydrogen nucleus?
In a Hydrogen nucleus there is a proton. Hydrogen is the only element to not have a neutron in it's nucleus.
What element does not have a neutron in the nucleus of a atom?
Hydrogen. In classical atomic theory, it contains only a proton.
Would the neutron also go with the proton in acid based reactions?
No, because Hydrogen is the element that reacts by either leaving it's proton from an acid or adding it's proton to a base and hydrogen does not have a neutron.
How many neutron are in the element hydrogen?
Depending on the isotope it could be 0,1 or 2. Usually it is 0.
