Each element has a uniqueatomic number, which is the number of protons it has. This is how we identify one element from another. Theperiodic table of the elementslists all of the discovered elements and their atomic numbers. Examples of elements include oxygen (O), carbon (C), and gold (...
An atom of an element has 10 protons. what is also true of that atom? What is an atom that has more protons than electrons? What is the lightest particle of an atom? What is an atom? Explain. What is an oxygen-18 atom? What two particles make up the mass of an atom?
In this topic, we will discuss the various things related to protons especially the mass of a proton. What Is An Atom? Atom is an atomic particle that makes up the entire universe. Furthermore, an atom is the smallest particle of an element. Most noteworthy, Atom is made up of three ...

Protons have arelative massof 1, which is the same as the relative mass of neutrons. Thenumber of protons in an atomis called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because itdefines the type of atom, i.e. whichelementit is an atom...
What element has a ground state electron configuration that contains five unpaired 5d electrons? An element in its ground state has the following electron configuration: (Ne)3s23p2. What is this element? An element ...
What chemical element has atomic number 118? Which element has 27 protons? Which element has 3 protons? What chemical element has 19 electrons? What element will be more reactive with another element? Explain. What type of chemical element is gold?
Notice that the general system for naming isotopes is the name of the element followed by a "-" followed by the mass number (=protons+neutrons) of that particular isotope, e.g. hydrogen-2. More Examples of Isotopes: There are two common isotopes of the elementchlorine. They are chlorine-...

matter. Each element is defined by the number of protons in its nucleus. The chemical elements are organized on theperiodic table of the elements. Each element has an atomic number and a symbol. The symbol may be based on the Latin name of the element and not be related to the English ...
