What are the unique electronic configurations and chemical properties of these series of elements, and how do they relate to their atomic numbers?

Complete and detailed technical data about the element $$$ELEMENTNAME$$$ in the Periodic Table. It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons. Since carbon is in the second row (or second period), it ... Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the ... Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (AMU). Together, the number of ... For ordinary nuclei composed of protons and neutrons, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of ... Element Gold (Au), Group 11, Atomic Number 79, d-block, Mass 196.967. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Isotopes are atoms of the same element that have the same number of protons (ie, atomic number, "Z") but a different number of neutrons. The number of protons in the nucleus is represented by "Z", the atomic number. The atomic mass of the element (number of protons plus the number neutrons) is ... The number of electrons and protons in an atom determines its chemical properties. Chemical properties include the specific ways that atoms and molecules react ... The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
