Answer:
Less than 7 ph value are acidic. Greater than 7 ph value are basic.
The total number of protons in this atom is 79 because an atomic number of an element is equal to the number of protons. Here, the atomic number is 79 after adding the given electronic configuration.
What are Protons?
Every atom has a proton, a subatomic particle, in its nucleus. The particle possesses an electrical charge that is positive and opposite to the electrons.
What is Atom?
A nucleus plus one or more electrons bound to the nucleus make up an atom. The quantity of protons or electrons in an element's atom determines how different it is from other similar elements. The atomic number of an element, which serves as its primary identification, is the sum of its protons or electrons.
What is Electronic configuration?
The arrangement of electrons in atomic or molecular orbitals within an atom, molecule, or other physical structure is known as the electron configuration.
Hence, the total number of protons in this atom is 79, after adding 2 + 8 + 18 + 32 + 18 + 1.
