Is there is a easiest way to remember the atomic number of the element in the periodic table? (2024)

FAQs

What is the atomic number easy? ›

The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons--the atomic number--are atoms of the same element.

The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.

Atoms are made up of protons, neutrons, and electrons. The number of protons in one atom of an element is its atomic number. Hydrogen has one proton, so its atomic number is one. Carbon atoms have six protons, so its atomic number is six.

Answer and Explanation:

If you are given the mass number and number of neutrons, you can find the atomic number by subtracting the number of neutrons from the mass number. This will result in the number of protons, which is also the atomic number for an element.

Step 1: Write the chemical formula Step 2: List all the atoms Step 3: Count the number of atoms of each element in 1 molecule. Step 4: Multiply the number of atoms of each by the coefficient. Step 5: Make sure your answer makes sense.

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

How do you remember the atomic configuration? ›

The more electrons an element has, the more orbitals it will have to fill. This is a memory aid that everyone that has ever taken general chemistry has seen. Follow the diagonals sequential, from tail to head. Remember that s gets two electrons, p gets six electrons, d gets 10 electrons, and f gets 14 electrons.
