and the number of protons in an atomic nucleus distinguishes one type of chemical atom from another. The simplest atom of all,hydrogen, has a nucleus composed of a single proton. The neutron has very nearly the same mass as the proton, but it has no charge. Neutrons are contained with pr...
Mass number (A) is a characteristic property of a specific isotope of an element, equal to the sum of the number of protons and neutrons in the nucleus.Citing this page: Generalic, Eni. "Mass number." Croatian-English Chemistry Dictionary & Glossary. 29 June 2022. KTF-Split. 15 Dec. ...
Thus, as summarized in Figure 2, we assumed that novice students would have a macroscopic continuous view of matter; as they progress in their studies, they would understand atoms as particles, followed by the understanding that these particles have protons, neutrons, electrons. Finally, they ...
Atomic number Number of protons and number of electrons in a NEUTRAL ATOM Mass number Number of protons + number of neutrons (ALWAYS A WHOLE NUMBER SINCE IT COUNTS PARTICLES) Isotope Atoms of the same element that have different masses. The number of protons is the SAME. The number of neutr...
