Answer to: Atoms of the same element that have different numbers of neutrons are called ___. A. isotopes B. ions C. isomers D. inert elements By...
4. In the nuclear chart, every square represents an isotope and those in the same horizontal line correspond to an element with given number of protons, Z. Therefore, the different squares along a line are various isotopes of the same element that have different number of neutrons, N. The ...
an arrangement of elements by increasing atomic number such that elements having similar chemical behavior are grouped in vertical columns atom Smallest particle of an element atomic number the number of protons in an atom isotope Atoms of the same element that have different numbers of neutrons...
The elements sodium, magnesium, and silicon ___. a. are isotopes of each other b. are in the same period of elements c. have the same number of neutrons d. are in the same group e. have the same mass number Find the atomic mass and mass num...
The numbers of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass of the number, A. The number of neutrons in ...
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. What is the difference between elements and compounds Class 9?
The number of neutrons in the nucleus, as you may have gathered from the above example, can however change, and we call atoms of the same element with different numbers of neutrons "isotopes". Sometimes these isotopes are stable, but often they are not and eventually decay. Discovery of ...
unit; the loss of an alpha particle, or helium nucleus (two protons and two neutrons), decreases the atomic number by two units; and the process of electron capture, in which an electron from an inner shell is drawn into the nucleus, corresponds to a decrease of atomic number by one ...
of +1, 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 ...
Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called ions. Atomic symbol: The atomic symbol (or element symbol) is an abbreviation chosen to represent an ...
