All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus.Answer and Explanation: Become a Study.com member to unlock this answer! Create your...
As the number of protons and neutrons in the nucleus increases, elements are much less likely to form stable, nonradioactive isotopes.Of elements that form nonradioactive isotopes, which has the highest atomic number? This problem has been solved!...
Atom is made up of three components namely protons, neutrons, and electrons. Using these components, the identity of the element can be known. The total number of protons and neutrons reveal an element's mass number while the number of protons ...

Atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior. 是原子序数(原子核中质子的数量)而不是原子的质量决定化学特性。 全句 We now know that atomic number (the number of protons in the nucleus), not...

an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an atom's element is identified by the number of protons.Ans...
The main building blocks of atomic nuclei are protons and neutrons, and it is convenient to describe the composition of an atom in terms of the number of protons and neutrons present in its nucleus. The number of protons contained in the nucleus of an atom is called the atomic number ( Z...
aluminum-27. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom ...
and has more electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. If an ion...
