SpletThe number of protons in an atom is equal to the atomic number of the element. For example, let’s use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element’s symbol. Since oxygen has an atomic number of eight, there must be eight protons total. SpletThe number of protons in the nucleus of an atom (# of positive charges) is equaled by the number of _______ in the electron cloud (# of negative charges) Mass Number The sum … bpn meaning spiritual support
What does the number of protons determine? - Quora
SpletCarbon has 6 protons and 6 electrons in its nucleus and outer shells. The number of neutrons in the nucleus of a carbon atom can vary, which results in different isotopes of the element. Carbon-12 has 6 neutrons in its nucleus and it is one of the most common isotopes of carbon. Other carbon isotopes are carbon-13, with 7 neutrons, and carbon ... SpletThe atomic number or proton number is defined as the total number of protons in the nucleus and is given the symbol Z. The number of electrons in an electrically-neutral atom is the same as the atomic number. The total electrical charge of the nucleus is therefore +Ze.
