Each element has a unique atomic number, which represents the number of protons inside the nucleus of one atom of that element. Protons are the positively charged particles inside an atom.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this an...
Protons have slightly less mass than the neutrons in the nucleus, but they are 1,836 times more massive than electrons. The actual mass of the proton is 1.6726 x 10^-27 kilograms, which is a very small mass indeed. The symbol "^-" represents a negative exponent. This number is a deci...
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-). It is the number of protons that determines the atomic number, e.g., H...
Every atom must have at least one proton in it. The number of protons in an atom is important, because it defines what chemical element the atom represents. For example, an atom with just one proton is hydrogen, an atom with 29 protons is copper, and an atom with 94 protons is plutoni...
The atomic number is the number of protons in an atom and the mass number is the number of protons plus the number of neutrons. The atomic number is... Learn more about this topic: Atomic & Mass Number | Overview & Difference from ...
An atom represents the most basic unit of an element that retains all of its chemical properties. On the other hand, a molecule is formed when two or more atoms, either of the same or different elements, bond together. 12 At its core, an atom consists of a nucleus with protons and neu...
Then write the number of charges in superscript. The number of protons in atoms and ions is the same. There is the only difference in the number of electrons. Answer and Explanation: Given Data: Electronic configuration of a...
- Atomic mass is defined as the weighted average of the masses of all the isotopes of a particular element. 2. Definition of Isotopes: - Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses. 3...
An element is defined by the number of protons in its nucleus, so this process transforms iron into heavier elements, like gold, in what is almost a form of cosmic alchemy. It is the radiation from the decay of the radioactive elements created during the r-process that makes the material...
Answer and Explanation: The net electrical charge of an ionic compound is zero. The unequal number of ions in a compound introduces the electric charge. The number of... Learn more about this topic: Ionic Compound | Formation, Properties & Examples ...
