Give the quantum number set for one electron in the 3p sublevel of a sulfur (S) atom.
IceJOKER [234]
<span>sulfurs electronic configuration is 1s2 2s2 2p6 3s2 3p4 so for the 3p sublevel principal quantum no - 3 angulum quantum no - 1 magnetic quantum no - (-1) or 0 or (-1) spin quantum no - (+1/2) or (-1/2) so the quantum numbers will be [ 3 , 1, -1 , +1/2 ] or [ 3 , 1, -1 , -1/2 ] [ 3 , 1, 0 , +1/2 ] or [ 3 , 1, 0 , -1/2 ] [ 3 , 1, 1 , +1/2 ] or [ 3 , 1, 1 , -1/2 ]

Of the three types of small energetic particles emitted from the core of certain atoms and characterized by rutherford, which is
FromTheMoon [43]

Atoms with neutrons, protons, and electrons. Only the neutron has no electrical charge; protons and electrons are the other particles that are electrically charged.

<h3>What do you know about atoms? explain.</h3>

The smallest component of ordinary stuff that makes up a chemical element is an atom.  Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass. The electric charges of the protons are positive, those of the electrons are negative, and those of the neutrons are zero. The atom is electrically neutral if the number of protons and electrons is equal.

For each of the following substances below, identify the type of bonding between the atoms. Justify your
solniwko [45]

Answer:

SF4 -Covalent bond

BaBr2 - Ionic bond

Ca - Metallic bond

Explanation:

Sulphur and fluorine are non metals. Nonmetal atoms combine by the sharing of electrons. This is also called a covalent combination(bond).

In BaBr2, a metal is combined with a nonmetal. This combination involves a transfer of electrons from the metal to the nonmetal forming an ion pair. This is otherwise called an ionic bond.

Atoms of a metal are held together by strong metallic bonds that involves positively charged cations and a cloud of electrons.

Consider the following equilibrium system: 3O2(g)  2O3(g); Keq = 1 Which equation compares the concentration of oxygen and ozone
Rashid [163]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

 <span>3O2(g) <--> 2O3(g); 

Keq = 1 = [O3]^2/[O2]^3 

So [O2]^3 = [O3]^2 

Thus A) is correct</span>
