(a)(i)Accept for the relative mass of electron[1] All relative charges are correct[1] All relative masses are correct(ii) The mass of an atom is concentrated in the nucleus of an atom. The electrons are of negl
. It therefore seemed desirable to find whether matter in which there is an excess of neutrons is electrically neutral. We have found that the charge on an argon atom (18 protons, 18 electrons and 22 neutrons) is not greater than 8×10−20eand that on a nitrogen molecule (14 protons, ...
Since the charge of the proton is a positive one, the number of protons vs. electrons in an atom is important in determining the charge of the atom. There is one atom that has only a single proton and no neutrons: hydrogen. As a neutron has no actual electrical charge, the only charge...
An ion has a mass number of 65, has 36 neutrons and has a charge of +1. Determine the number of electrons in this ion. An atom or ion has 42 neutrons, 36 protons and 36 electrons. Determine the charge of this atom or ion. What is the mass nu...
then so long as the number of protons and electrons are equal then their charges cancel out and atoms are electrically neutral. Remove an electron from around an atom, however, and this upsets the balance between the cumulative charges of the electrons and the protons, and the atom becomes ...
Students should consider how models of atomic structure have developed over time, as new evidence has become available. Know the structure of an atom in terms of electrons, protons and neutrons.CIE AS ChemistryIdentify and describe protons, neutrons and electrons in terms of their relative charges...
For an element , if atomic number (Z) and mass number (A) are 29 and 63 respectively . Then the number of protons , neutrons and electrons respectively are :- View Solution The atomic weight of an element is 39.The number of neutrons in its nucleus is one more than the number of pr...
The superheavy nuclei with magic number of protons/neutrons are 2 9 8 114, 3 1 0 114, 3 0 6 122, 3 1 8 122, 3 0 8 124, 3 1 0 124, 3 1 0 126 and 3 2 2 126. All the possible decay modes have been studied by using three different models such as modified generalized ...
Question: The neutrons of an atom have ___ charges and are located ___ the nucleus. Components of Atoms: Elements are made up of atoms. Atoms are the smallest units of life, and are made up of three subatomic particles: protons, neutrons, and electrons. Answer and Explanation: Be...
