Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
What is used to show electrons in an atom?
Four quantum numbers are used to describe electrons in atoms.
Why scandium and boron in different groups?
They have different atomic numbers.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
What is the total number of protons if a sample of scandium has a mass of 7.9027?
Interesting question! Let us proceed slowly. Scandium has 21 protons per atom and 6.022 X 10^23 atoms per mole. 21 X 6.022 X 10^23 = 1.26 X 10^25 protons per mole of Scandium. 7.9027 grams Scandium (1mol/44.96g ) = 0.176 mol Scandium 0.176 mole Scandium X 1.26 X 10^25 protons Scandium = 2.22 X 10^24 total protons in 7.9027 grams of Scandium. ( you can put this all into one conversion string if you like )
How many quantum number are required to specify a single atomic orbital?
All four quantum numbers i.e principle ,azimuthal or subsidiary, magnetic and spin quantum numbers are required to specify a single atomic orbital.
Write four quantum numbers for 1s electron?
How are electrons arranged in the quantum mechanical model of an atom
How are quantum numbers different from an address?
The four quantum numbers, n, l, m1, and ms, are all solutions to Schrödinger's equation. These numbers are used to assign each electron in an atom an "address." They "uniquely characterize an electron and its state in an atom" ("Quantum Number").

Quantum numbers for Br?
What are the quantum numbers of Br?
How many mass numbers does scandium?
44.9559
What shell are they in scandium?
Scandium has four electronic shells with 2, 8, 9, 2 electrons.
What is used to show electrons in an atom?
Four quantum numbers are used to describe electrons in atoms.
How many electrons can have the quantum numbers n 5 ℓ 0 ml0?
There can be two electrons with those quantum numbers in an atom. Each electron is completely described by four quantum numbers. The one that's missing in the list provided is ms, which can have only two possible values (+1/2 and -1/2).
Why scandium and boron in different groups?
They have different atomic numbers.

What are quantam numbers?
from Max Planck's theory, quantum numbers are units of energy.
