Do isotopes have the same atomic number? In order to find an accurate age of a living organism, we have to compare the amount of carbon to what other isotope? How do the nuclei of different isotopes of an element vary? If Atom #1 has 19 protons and 22 neutrons, and Atom #2 has 20...
if an isotope has 114 protons, it is a stable isotope. Moreover, if there are 126 or 184 neutrons present, they are also stable isotopes. In addition, if the ratios between protons and neutrons in an atom are even numbers, then these isotopes are most probably...
different isotopes of an element. b. a neutral atom and an ion of the same element. Explain how the fission can be slowed in the nuclear reactor. Is uranium-235 more likely to undergo nuclear fusion or nuclear fission? Explain. A nuclear scientist attempts to perform exp...
Figure 1: A Model of a Homonuclear Diatomic Molecule The two atoms of the homonuclear molecule are same; thus theelectronegativityis also equal. Then the bond electron pairs between the two atoms are equally distributed, and the chemical bond between the two atoms isnonpolar. There can be sin...
Atom:There is a nuclear force that holds the nucleus together. And, most of the mass of an atom lies in its nucleus. There is an electric force that is used to keep the atoms together.Answer and Explanation: According to the Rutherford model of the atom, the nucleus is a positive...
How does the mass of a nucleon compare with the mass of an electron? Nucleon: Nucleon is a term used to refer to either a proton or a neutron. The term "nucleon" is not really necessary, but it is used to distinguish protons and neutrons that are bound to the nucleus of ...
Isotopes vs Isobars Atoms are the small building blocks of all existing substances. There are variations between different atoms. Also, there are var
There are about 118elementsin the periodic table according to theiratomic number. An element is a chemical substance that consists of only a single type of atoms; hence, they are pure. Allotropes are different forms of the same compound while isotopes are different forms of the same element....
One neutron is added to the nucleus of an atom of Carbon-12. How has the atom been changed? Does it have a greater atomic mass? Compared to an electron, a positron has: a. the same mass and charge b. different mass and charge c. the same charge, but a diffe...
The compact part of a substance originates from an atom. Protons, neutrons along with electrons as well constitute an atom. When a group of atoms unites together through chemical bonds, then a molecule formsAnswer and Explanation: The atomic theory presented by Democritus as well as Joh...
