The set of quantum numbers for the electrons in Be atom are (2, 1, -1, 1/2), (1, 0, 0, 1/2), (1, 0, 0, -1/2) and (2, 0, 0, -1/2)

Explanation:

There are 4 quantum numbers:

Principal Quantum number (n) specifies the energy of the electron in a shell.Azimuthal Quantum number (l) specifies the shape of an orbital. The value of it lies in the range of 0 to (n-1)Magnetic Quantum number (m) specifies the orientation of the orbital in space. The value of it lies in the range of -l to +lSpin Quantum number (s) specifies the spin of an electron in an orbital. It can either have a value of or

Berylium (Be) is the 4th element of periodic table having electronic configuration of

For electrons in 1s-orbital, the quantum numbers can be:

For first electron:

For second electron:

For electrons in 2s-orbital, the quantum numbers can be:

For first electron:

For second electron:

Hence, the set of quantum numbers for the electrons in Be atom are (2, 1, -1, 1/2), (1, 0, 0, 1/2), (1, 0, 0, -1/2) and (2, 0, 0, -1/2)

Tropical easterlies is mostly likely your answer correct me if i’m wrong

Matter- occupies space and possesses rest massno matter is the opposite
