The identity of an element is defined Fluorine (F) 2,7 Name: Fluorine Symbol: F Atomic Number: 9 Atomic Mass: 18.998404 amu Melting Point: -219.62 °C Boiling Point: -188.14 °C Number of Average atomic mass = f1M1 + f2M2 +… + fnMn where f is the fraction representing the natural abundance It has a low melting point (27 oC, 81 oF) and, if enough of it could be accumulated, Scientists there trapped up to ten thousand francium atoms at a time using laser Francium's isotopes, with mass numbers ranging from 200 to Isotopes 36 and 37 are found in equal proportions. To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons.
Most of the atomic mass of a substance is made up of protons and neutrons. Therefore, it is almost equal to its mass number. Average atomic mass = f 1 M 1 + f 2 M 2 +… + f n M n where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope.

2014-02-24 Atomic mass can be defined as the total mass of one atom of any given element. The unit of atomic mass is called the unified atomic mass unit (denoted by ‘u’). Most of the atomic mass of a substance is made up of protons and neutrons. Therefore, it is almost equal to its mass number. Average atomic mass = f 1 M 1 + f 2 M 2 +… + f n M n where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol. 2013-09-17 2020-07-26 Atomic mass.
