Question

Select the words that correctly fill in the blanks for this statement:

The p sublevel has ________ orbitals that are ________-shaped.

three, dumbbell
three, spherical
five, dumbbell
five, spherical

Answer 1

Answer : The correct option is, three, dumbbell.

Explanation :

As we know that there are many sub-levels which are s, p, d, f, g and so on. The sub-level are oriented in three directions along the x, y and z axis.

The 's' sub-level has one orbital that are spherically shaped.

The 'p' sub-level has three orbitals
`(p_x,p_y,p_z)` that are dumbbell shaped.

The 'd' sub-level has five orbitals
`(d_(xy),d_(xz),d_(yz)d_(z^2),d_(x^2-y^2))` that are double-dumbbell shaped.

The 'f' sub-level has seven orbitals
`(f_(x(x^2-3y^2)),f_(y(x^2-3z^2)),f_(y(3x^2-3y^2)),f_(xz^2),f_(z^3),f_(yz^2),f_(xyz))` that are complex flower shaped.

Hence, the 'p' sub-level has three orbitals that are dumbbell shaped.

Answer 2

The correct answer is option A. Three, dumbbell.

The p sublevel has __three_orbitals that are _dunmbbell_-shaped.

The three orbitals of the p sublevel are oriented in three directions along the x, y and Z axis. The orbitals are called px, py and pz. Each p orbital can have a maximum of 2 electrons. Since there are three p orbitals, the p sublevel can have a maximum of 6 electrons.
