The diagram below shows the different phase transitions that occur in matter.
solmaris [256]

Answer:

# 5

Explanation:

The question describes silver being "poured" into a mold and cools to become a solid bar. This is the phase of liquid to solid. When a element cools down below it's freezing points to become a solid.

<u>Liquid to Solid Definition:</u>

Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.

The atoms of which elements are least likely to form chemical bonds? Check all that apply.
svetoff [14.1K]
The elements that apply are argon, neon and helium. These elements are called inert gasses and have unique properties that make them unreactive. These elements are so unreactive that they are classified as chemically inert.
The elements belong to a group in the periodic table known as the Noble Gases. They belong to family 18 of the periodic table and have atoms with 8 valence electrons. This configuration causes the gases to be unreactive.

Complete the table below by filling in the principal quantum number n and angular momentum quantum number l for each electron su
Alja [10]

Answer:

For 4f  the principal quantum number, n is 4 and the angular momentum quantum number l is 3

7s: n = 7 and l = 0

4p: n = 4 and l = 1

7p: n = 7 and l = 1

Explanation:

The principal quantum number gives the energy level of the electron in an atom. It shows the shells in which an electron is in an atom.

if n = 1, 2, 3, 4...; it corresponds to K, L, M, N... shells in an atom

The numerical coefficient of the subshell gives the pricipal quantum number.

for instance in 4f, the principal quantum number, n is 4  because 4 is the coefficient.

The angular momentum quantum number, l gives the energy sublevel or subshell.

Angular momentum quantum number has integral values, l = 0, 1, 2, 3... which correspond to  s, p, d, f,..  orbitals.

Thus for 4f  the principal quantum number, n is 4 and the angular momentum quantum number l is 3

similarly, for 7s: n = 7 and l = 0

4p: n = 4 and l = 1

7p: n = 7 and l = 0

using similar approach for others

Lanthanides and actinides are kept separately in the periodic table. why? ​
liberstina [14]
The lanthanides and actinides are separated from the rest of the periodic table, usually appearing as separate rows at the bottom. The reason for this placement has to do with the electron configurations of these elements.
