Technetium (Tc) has 43 protons.
A nuclide is identified by the number of protons in its nucleus, known as the atomic number, and the total number of protons and neutrons, known as the mass number. These two properties determine the unique identity of a specific nuclide.
The number of protons in a nuclide is determined by its atomic number, which is unique to each element. The atomic number is typically listed in the periodic table and represents the number of protons in the nucleus of an atom.
A correct representation for a nuclide of radon in atomic symbol notation would be ^22286 Rn. This indicates that the nuclide has 222 nucleons (sum of protons and neutrons) and an atomic number of 86 (number of protons).
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
This is a stable isotope of sulfur: 1616S.
The mass number of a nuclide is found by adding together the number of protons and neutrons in the nucleus of the atom. It is represented by the symbol A in the nuclide symbol.
Silicon has 14 protons and 14 neutrons. -I hope this helped-
The nuclide symbol for an element is represented as [ \text{A}{\text{Z}}^{\text{Element}} ], where A is the mass number (protons + neutrons) and Z is the atomic number (number of protons). For an element with 12 protons and 13 neutrons, the mass number (A) would be 25 (12 + 13) and the atomic number (Z) would be 12. Thus, the nuclide symbol is [ \text{^{25}{12}\text{Mg}} ], indicating it is magnesium.
The nuclide notation for an atom with 13 protons and 5 neutrons is (^{18}_{13}Al), where the superscript is the sum of protons and neutrons (18) and the subscript is the atomic number (13) for the element aluminum (Al).
It has 43 protons 43 neutrons and 43 electrons.
The atom with 55 protons and 78 neutrons is silver-133. Therefore, the correct nuclide symbol would be (_{47}^{133}Ag).
