A single atom of an element has 11 protons, 11 electrons, and 12 neutrons. Which element is it? What is the name of the element that has an atomic number of 8? An atom of an element has 10 protons. what is also true of that atom?
Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes referred to as 'Z', defines the type of atom, i.e. which element it is an atom of. As indicated in the List of Chemi...

- Hint: Atomic mass of an element can be determined from knowing the atomic number of the element and the number of neutrons present. In case of sodium the atomic number is 11.Formula used: Atomic number + Number of neutrons Complete step by step answer:...
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. ...
