Because protons are units of matter, atomic numbers are always whole numbers. At present, they range from 1 (the atomic number of hydrogen) to 118 (the number of the heaviest known element). As more elements are discovered, the maximum number will go higher. Theoretically, there is no maxi...
Step-by-Step Solution:1. Identify the Atomic Number of Sodium: - The atomic number of sodium (Na) is 11. This means that sodium has 11 protons in its nucleus.2. Understanding the Electronic Co
number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons.
The total number of unit positive charges present in the nucleus of an atom is known as its Atomic Number which is equal to the number of protons in the nucleus of an atom. Atomic Number for any two different atoms is never same and hence can be used to distinguish two different atoms...
