What is an atom that has varing numbers of neutrons?

A single atom that has varying numbers of neutrons is undergoing a nuclear reaction. However, the questioner probably meant, "What is the name for different atoms of the same element that have differing numbers of neutrons?", and the answer to that question is "isotopes"


What is the name of the smallest paricle of an element that has the properties of that element?

An atom is the smallest particle of an element that has the properties of that element. The atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element. No Sub-Atomic Particles have any characterisitics of an element. It is the collective arrangement of electrons and protons (and usually neutrons) which gives an element its characteristics. An atom is the smallest particle that has elemental characteristics.


What name do we give to the tiniest piece of element?

The smallest particle of an element that still has all the properties of an element is an atom of that element.


An unknown atom has 26 neutrons and an approximate atomic mass of 48 amu. What is the name of this element?

This element has 26 neutrons, so its atomic number would be 26. Given an approximate atomic mass of 48 amu, this corresponds to the element iron (Fe).


An unknown atom has 26 neutrons and an approximate atomic mass of 48 What is the name of this element?

That has an atomic mass of (45 + 56), or 101.


What is the name of an atom that has 3 protons 4 neutrons?

This is an easy problem to solve if you have a Periodic Table of Elements.# protons + # neutrons = atomic number3 + 4 = 7The element with the atomic number 7 is Nitrogen.


How do you obtain the mass number of an atom?

in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!hope this helped!!! :)


What is the name for atoms of an element that have different masses?

An atom or element that have different masses are known as isotopes.
