Nuclei that contain the same number of protons but a different. number of neutrons are known as isotopes.
9 wrz 2017 · This document defines and provides examples of atoms, elements, molecules, and compounds. It states that atoms are the basic unit of a chemical element and are made up of protons, neutrons, and electrons.
2 gru 2018 · The isotopes are identified through their mass number which is the sum of the number of protons and the number of neutrons in an atom. Information on the subatomic composition of an element may be represented through shorthand notations.
Neutrons are neutral or uncharged. Protons have a positive (+) charge, and electrons have a negative (-) charge. NEUTRAL atoms have NO CHARGE because the number of protons is equal to the number of electrons.
6 gru 2016 · The number of protons determines the element and its atomic number. - Neutrons have no charge and have a mass slightly larger than protons. Along with protons, they make up the nucleus of atoms. - The atomic number is the number of protons in an atom's nucleus and identifies the element.
- Heavier protons and neutrons in the center or nucleus and the smaller electrons are found outside of the nucleus in shells of specific energy. - The outer electrons and their arrangements in specific energy levels are responsible for the chemistry of the element. - The number of protons (atomic number) determines the identity of the atom NOT the
29 lip 2022 · Describe the locations, charges, and masses of the three main subatomic particles. Determine the number of protons and electrons in an atom. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion. Define the atomic mass unit and average atomic mass.
