What is the smallest value of the principal quantum number that can describe an "f" orbital? What does the angular quantum number, l, tell us? a) the number of electron shells an atom has. b) the number of orbitals the electron shell of an atom has. c) which direc...
1 An atom of an element has an atomic number of 6 and a mass number of 12.(a)Using this information, complete the table to show the numbers of protons,neutrons and electrons in one atom of this element.(2)number of protons number of neutrons number of electrons(b)The Periodic Table ...
The atomic number of an element is equal to the number of protons in its nucleus. In a neutral atom, the number of protons equals the number of electrons in shells which is the energy level around the nucleus. Isotopes are atoms with the same atomic number but distinct neutron numbers, ...

1.Understanding the Question: The question asks about the significance of the number of electrons in the outermost shell of an atom. We need to determine whether this number relates to the "group" or "period" of the periodic table.
The border of the circle is given a numerical value. This value is the principal quantum number. Another way to depict the principal quantum number is to show the subshells of the atom. The furthest-out subshell has the same value as the principal quantum number. Therefore, if an atom ...
In quantum mechanics, the principal quantum number (symbolized n) is one of four quantum numbers which are assigned to all electrons in an atom to describe that electron's state. As a discrete variable, the principal quantum number is always an integer. As n increases, the number of electron...
