What is the mass in grams of a single atom of each of the following element? Hg? Anybody that can help it would be greatly appreciated
The mass in grams of a single atom varies depending on the element. The standard unit for measuring atomic mass is atomic mass units (amu) or daltons (Da). One amu is equal to 1/12th of the mass of a carbon-12 atom, which is approximately 1.66 x 10^-24 grams.
The mass of an atom is determined by adding up the masses of its protons, neutrons, and electrons. The majority of an atom's mass comes from its protons and neutrons, which are located in the nucleus. Electrons have a much smaller mass and are located in the electron shells surrounding the nucleus.
The atomic number of an atom is equal to the number of protons in its nucleus. Mass number, on the other hand, is equal to the number of protons plus the number of neutrons in the nucleus. Therefore, the mass of an atom increases with its atomic number.
Expressing the mass of an atom in atomic mass units allows for easier comparison between different elements. Since the mass of an atom is extremely small, using grams or kilograms would result in very small numbers. Atomic mass units provide a more convenient scale for measuring atomic mass.
The mass of an atom does not change under normal circumstances. The nucleus of an atom is very stable, and the mass of its protons and neutrons remains constant. However, nuclear reactions can cause changes in the number of protons and neutrons, resulting in a change in atomic mass.
