WebThe parts of the atoms become the electron, neutron, and electron. The protons plus neutrons inhabit the atom’s nucleus (or center), while electrons spin around the outside of the nucleus. ... The atoms in each unique element have a specific number of protons. Forward example, oxygen can two atoms so its atomic number is 2. WebAn early model of the atom was developed in 1913 by the Danish scientist Niels Bohr (1885–1962). The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun.

WebAtomic mass of Oxygen is 16 we know that Mass number=No. of proton+No. of neutron No. of neutron in O atom is =16−8=8 No. of proton in O atom =8 (atomic number=no of proton) No. of electron in O atom=8 (no. of proton=no.of electron for neutral atom) In O −2 ion No. of electron =8+2=10 1mole=6.022×10 23 ions WebThe total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. WebChemical elements are found in different versions, called isotopes. Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. For example, there are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18. Each isotope of oxygen contains 8 protons, but differs in the number of ... cpu for video editing amd
