Only hydrogen has un-isotopic atoms without a neutron. Hydrogen can sometimes though have one or so neutrons in its isotopes. The other elements must have neutrons to keep the protons from repelling each other in the atom's nucleus.
All element contain neutrons except hydrogen.

The smallest unit that shows the properties of an element is an atom, and yes, an atom has protons and neutrons in the nucleus.
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
All elements have neutrons and protons within the nucleus.
All neutrons (of all elements) are located in the nucleus (as all ptotons are)
The nucleus is made of protons, neutrons and electrons. These element move in and out of the nucleus depending on the external environment.

There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
The only element that has one proton and no neutrons is a hydrogen atom.
Number of neutrons in the nucleus.
An element's nucleus basically contains protons and neutrons. Electrons rotate around the nucleus of an atom.
