How many different principal quantum numbers can be found in the ground-state electron configuration of nickel?A) 2.B) 3.C) 4.D)
Naddik [55]

Answer:

C) 4.

Explanation:

Hello!

In this case, since the electron configuration of nickel at its ground-state, considering 28 as its atomic number and the number of electrons it has in one atom, is:

Ni^{28}:1s^2,2s^2,2p^6,3s^2,3p^6,4s^2,3d^8

We can see it has four energy levels, 1, 2, 3 and 4, which are related to the following principal quantum number, that describes the energy of an electron in the atom and its most probable distance with respect to the nucleus.

Therefore, nickel has C) 4 different principal quantum numbers.

Best regards!

TRUE or FALSE: Any measurement that has been cubed is volume.
zmey [24]

Answer:

True

Explanation:

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.

What is the total number of molecules in 11.2 liters of N2 gas at STP
scoray [572]
Molar volume at STP = 22,4 L

1 mole -------------- 22,4 L
 x mole -------------- 11,2 L

x = 11,2 / 22,4

x =  0,5 moles of N2

1 mole --------------- 6,02.10²³ molecules
0,5 moles ------------ y molecules

y = 0,5 . 6,02.10²³

y = 3,01.10²³ molecules
