The number of protons in a particular nucleus, i.e. the atomic number of the atom, is equal to the number of electrons in a neutral (nonionized) atom. The arrangement and behaviour of these electrons determine the interactions of the atom with other atoms and thus govern chemical properties...
An atom is composed of three particles, namely,neutrons, protons and electronswith hydrogen as an exception without neutrons. Every atom has a nucleus that bounds one or more electrons around it. The nucleus has typically a similar number of protons and neutrons which are together known as nucle...

In the presence of heavier elements, particularly carbon and nitrogen, a catalytic sequence of nuclear reactions aids the fusion of protons to helium (H. A. Bethe and C. F. von Weizsäcker, 1938) (Fig. 1.4). The overall reaction is precisely as before with the evolution of 26.72 MeV,...
a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and eight neutrons, although the two masses will be different. Nuclei with the same number of protons but different numbers of neutrons are said to beisotopesof each other. All ch...
The charge of an ion with 12 protons and 11 electrons is -1. True False True or false? A rubidium-82 atom has an equal number of protons and electrons in its nucleus. True or False: Sulfur likes to gain two electrons. True or false? The d su...
Atoms: Atoms are comprised of three basic components. In the nucleus, there are protons (positive charge) and neutrons (no charge). These are where the vast majority of the weight is and will determine what type of atom this is. Electrons (negatively charged) orbit relatively far away ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
Europium–ethene species may be synthesized at 12 K by the codeposition of europium atoms with ethene, neat or diluted with argon or xenon.1 These complexes, which are of the type Eu(C2H4) and Eu(C2H4)n, decompose above 50 K, and were characterized by UV–visible and IR spectroscopy. ...
