Webb1 jan. 2024 · Nuclear stability is attained for low atomic numbers when the number of protons is approximately equal to the number of neutrons (i.e., at Z/N ≈ 1). Above calcium ( Z = 20), no stable nuclide exists with equal numbers of protons and neutrons, for as Z increases, the repulsive Coulombic forces increase at a greater rate than the attractive … WebbThe atomic number represents the number of protons in an atom A (n) _____ refers to two or more atoms held together by covalent bonds. shell ion isotope molecule community molecule What name is given to the bond between water molecules? polar covalent ionic hydrophobic hydrogen single (nonpolar) covalent hydrogen

WebbThe atomic number is a fundamental property of an element that categorizes the element and its properties. It represents the number of positively charged particles, called protons, present in the atom's nucleus. WebbWe know that the atomic number of carbon is 6 and the atomic mass number is 12. Neutron = 12 – 6 = 6. Therefore, the number of neutrons in carbon is 6. Based on the atomic number of the element, the mass number, and the number of neutrons, three things can be considered. Namely, isotope, isobar, and isotone. cultural rights in the philippines

Silver is a chemical element with atomic number 47 which means there are 47 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. east lothian homes for sale
