Question

What are the atomic properties?

1.Atomic number
2.Chemical symbol
3.Number of protons
4.Atomic weight
5.Number of electrons
6.Number of valence electrons
7.Number of electrons in the second shell
8.Number of neutrons

Answer 1

Atomic properties include atomic number, chemical symbol, number of protons, atomic weight, number of electrons, number of valence electrons, number of electrons in the second shell, and number of neutrons.

Step-by-step explanation:

Atomic Properties

1. Atomic number: The number of protons in the nucleus of an atom. It defines the identity of an element.
2. Chemical symbol: A shorthand notation for an element, usually a one- or two-letter abbreviation.
3. Number of protons: The same as the atomic number, it determines the element's identity.
4. Atomic weight: The average mass of an element's atoms, taking into account the different isotopes and their abundance.
5. Number of electrons: In a neutral atom, the number of electrons is equal to the number of protons.
6. Number of valence electrons: The electrons in the outermost shell of an atom, involved in chemical reactions.
7. Number of electrons in the second shell: The second shell can hold up to 8 electrons.
8. Number of neutrons: The difference between the atomic weight and the atomic number, or the mass number minus the number of protons.
