Periodic Table: Element Identification F1, F2, F17, F18 Identify the element from the periodic table by its atomic number and chemical symbol. For more information, visitHow can the answer be improved? f2 atomic number

A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i. e. the same atomic number, or Z). Therefore, the elements can be listed by the number of protons in the atom of each element as listed below.

The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon12, has an atomic mass of 12 amu. Other atoms dont generally have roundnumber atomic masses for reasons that are a little beyond the scope of this article. The atomic number of fluorine is 9, so a (neutral) F2 molecule has a total of 18 electron, or 14 valence electrons (excluding the four 1s electrons). The (F2) ion has one more valence electron, or 15.f2 atomic number Sep 20, 2018  To find the number of neutrons in an element, subtract the atomic number from the mass number. Here are a couple example: A single helium (He) atom has a mass number of 4 and an atomic number of 2. It must have 4 2 2 neutrons. A sample of silver (Ag) has an average mass number of 108 (based on the periodic table) and an atomic

It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon. The atomic number is the number of protons (positively chargedparticles) found in an atom's nucleus. It is also equal to the number of electrons (negatively chargedparticles) in the atoms electron
