What determines an element
WebJul 20, 2024 · The number of protons determines an atom's identity as a chemical element; the number of neutrons determines the isotope of that element. Textbooks often depict a nucleus as so many protons and neutrons stuck together like gumdrops, but real nuclei are far more complicated. Although it's made of discrete particles, the average … WebMar 19, 2024 · The nucleus (or center) of an atom is made up of protons and neutrons. The number of protons in the nucleus, known as the "atomic number," primarily determines where that atom fits on the Periodic Table. The number of protons in the nucleus also defines in large part the characteristics of an atom—is it a gas or a metal, for example. the palm las vegas reviews

It is the energy released (per mole of X) when this change happens. First electron affinities have negative values. For example, the first electron affinity of chlorine is -349 kJ mol -1. shutters decor ideas
