The atomic number of an element refers to the number of protons in its nucleus. The atomic mass of an atom is approximately the number of neutrons and protons present in the nucleus. The mass of electrons is negligible. Answer...
Isotopes - isotope: atoms of the same element that have different numbers of neutrons - Carbon, as found in nature, is a mixture of isotopes, including atoms of carbon-12, carbon-13, and small amounts of carbon-14. Isotopes atomic weight - The atomic weight of an element is the weighted...
5Which statement explains why isotopes of the same element have the same chemical properties?C A They have a different number of neutrons in the nucleus. B They have the same number of neutrons in the nucleus. C They have the same number of outer shell electrons. D They have the same nu...
C A Their physical properties are different because they have different proton numbers. B Their atomic masses are different because they have different numbers of electron shells. C They have the same chemical properties because they have the same number of electrons in their outer shells. D They...
Ions Ions have differing numbers of electrons, which gives the atom an electrical charge. Fewer electrons gives a positive charge, more electrons gives a negative charge. Example: Potassium usually loses one electron, and it’s symbol becomes K+1. Chlorine usually gains one electron, and it’s...
Isotopes are atoms of an element that contain different number of neutrons in their atomic nucleus. They have the same atomic number, i.e., same number of protons (of course an equal number of electrons), but differ in their atomic mass due to the neutron numbers. For example, the three...
Subatomic particles are the small particles that make up atoms. There are three main types of subatomic particles in an atom, protons, neutrons and electrons.Answer and Explanation: The subatomic particle that identifies isotopes is neutrons. Isotopes are atoms that have a different number of ...
Hi guys , I need help in understanding why Isotopes have different physical properties. My textbook says that Isotopes have different physical properties as isotopes have different number of neutrons. The difference in the number of neutrons affect the "mass" and the physics properties of a substan...
Atoms are made of three different subatomic particles: protons, neutrons, and electrons. Protons have a positive charge and reside in the nucleus at the center of the atom. Electrons are negatively charged and orbit the nucleus. Neutrons have a neutral charge and they reside in the nucleus with...
Answer Expert Verified The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but have same atomic number. When we write an isotope, the number at the end of the isotope's name is ...
