An electron in an atom is known to be in a state with magnetic quantum number ml=0. What is the smallest possible value of the p

rusak2 [61]

Answer:

Explanation:

The principal quantum number, n, showsthe principal electron shell. which can inturn be describe as the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is. n can be any positive integer starting at 1, as n=1 designates the first principal shell (the innermost shell). When an electron is in an excited state or it gains energy, it may jump to the second principle shell, where n=2

As the energy of the electron increases, so does the principal quantum number, e.g., n = 3 indicates the third principal shell, n = 4 indicates the fourth principal shell, and so on. n=1,2,3,4…

On the other hand, the magnetic quantum number ml determines the number of orbitals and their orientation within a subshell. Consequently, its value depends on the orbital angular momentum quantum number l. Given a certain l, ml is an interval ranging from –l to +l, so it can be zero, a negative integer, or a positive integer. ml=−l,(−l+1),(−l+2),…,−2,−1,0,1,2,…(l–1),(l–2),+l

note also that: The orbital angular momentum quantum number l determines the shape of an orbital, and therefore the angular distribution. The number of angular nodes is equal to the value of the angular momentum quantum number l. Each value of l indicates a specific s, p, d, f subshell (each unique in shape.) The value of l is dependent on the principal quantum number n. Unlike n, the value of l can be zero. It can also be a positive integer, but it cannot be larger than one less than the principal quantum number (n-1): l=0,1,2,3,4…,(n−1).

So the answer is 1

A student fills two syringes: one with air and the other with an equal volume of

Shtirlitz [24]

Here we need to see the differences between a liquid and a gas, and how that affects the volume and effects of pressure on them.

The correct option is:

Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.

So we have two syringes, one with air and the other with water.

The student applies the same amount of pressure to both of them, but as water is denser than air, in a given change dV of volume in the syringe, the mass of water is larger than the mass of air.

This means that for the same pressure, we should expect the change in volume to be smaller in the syringe with water.

Why this happens?

Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.

This means that for the air is easier to be compressed (the distance between particles is larger, so the same pressure compresses more a gas than a liquid) and exit the syringe than for the water, and this translates to the change in volume per unit of pressure applied, which is larger for gases than liquids.
