Sodium is a white-silvery metal that belongs to Group 1 (alkali metals) and Period 3 elements in the periodic table. An element is a pure substance made up of only one type of atom (the simplest unit of an element comprises sub-atomic particles: electrons, protons, and neutrons). In ad...
To calculate the number of electrons, protons, and neutrons in a sodium atom, we can follow these steps:Step 1: Identify the Atomic Number and Mass Number - The atomic number (Z) of sodium is given as 11. - The mass number (A)

Atomic mass is the relative weight of the protons and neutrons in an atom. Remember, atoms are composed of protons, neutrons, and electrons. Electrons are much smaller than either protons or neutrons, so we consider their mass negligible. The unit used for atomic mass is atomic mass units (...
If all the sodium chloride (table salt) in the oceans could be extracted and dried, it would cover the entire surface of the USA to a depth of almost a mile and a half (about 2.3 km). The same salt could cover all the land on Earth to a depth of almost 500 feet (150 m). ...
