From the periodic table, you can gather information like the atomic number (number of protons), atomic mass, electron configuration, and chemical symbol of an atom. Additionally, you can learn about the element's group (column) and period (row), which can give insights into its properties and reactivity.
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
The atomic number on the periodic table corresponds to the number of protons in an atom's nucleus. It uniquely identifies each element since no two elements have the same number of protons. Elements are arranged on the periodic table based on their atomic number.
Which element will be oxidized and which will be reduced
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
the atomic number <<< apex : )
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.

It identifies the element.
Plot
An element that tends to give up electrons has a positive oxidation number. This is because when an element loses electrons, it becomes positively charged.
Number of protons = the atomic number of the element

Atomic no. helps to know 1. the position of element in the periodic table2. Common properties3. Electronic Configuration4. Common electrovalencies and oxidation states.5. Many other properties.
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
