In a atom the number of electrons are equal
WebSince an atom must have an overall neutral charge, the number of protons and electrons found within an atom of an element must be equal. Therefore, every atom of tungsten also contains 74 electrons. The mass number of an atom is calculated by adding together the number of protons and neutrons that are found within that atom, as shown below. WebIts chemical behavior is determined by the atomic number 2 (the number of protons), which equals the normal number of electrons; the stability of its nucleus (that is, its radioactivity) varies with its atomic weight (approximately equal to the number of protons and neutrons). The most well-known form of plutonium, for example, has an atomic ...

WebMar 24, 2024 · atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number. WebAn atom contains equal numbers of protons and electrons. Since protons and electrons have equal and opposite charges, this means that atoms have no overall electrical charge. For example,...
WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to … The electrons in an atom are arranged in shells that surround the nucleus, with … Valence electrons are the electrons in the outermost shell, or energy level, of an … http://www.scienceline.ucsb.edu/getkey.php?key=4554
