The valence electrons are located in an atom's outermost energy level

<h3>Further explanation  </h3>

In an atom, there are levels of energy in the shell and subshell  

This energy level is expressed in the form of electron configurations.  

Electrons fill the orbitals based on the Aufbau principle, namely the filling of electrons starts from the lowest energy level

  • Electron dots

Usually used in describing Lewis structures, placed around the element

  • Quantum electrons

Each orbital in an atom consists of 4 quantum numbers  : n, l, ml, ms

Each electron has a different quantum number and this conforms to Pauli's rule: no electrons have the same 4 quantum numbers

  • Valence electrons

Valence electrons are electrons used in a chemical bond , and  in an atom's outermost energy level

  • Noble-gas electrons

Noble gas has a stable electron configuration of 8 valence electrons which guides the formation of chemical bonds called the octet rule

How would you figure the number of neutrons in an atom?
Sonbull [250]
<span>Mass Number = (Atomic Number) + (Number of Neutrons) so you solve for the Number of Neutrons and you get:
Number of Neutrons = (Mass number) - (Atomic Number) 

Mass Number equals protons plus neutrons, round atomic weight to nearest whole number
Atomic Number equals number of Protons</span>

What is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution?
OverLord2011 [107]

Answer: -

Molarity is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution.

Explanation: -

Molarity is defined as number of moles of solute dissolved per litre of the solution.

Molarity symbol is M.

1 M = 1 mol / L

Thus molarity is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution

Mg(OH)2 + HCl --&gt; MgCl2 + H2O
Rashid [163]
I am guessing you want us to balance this equation so.
To balance, we add another molecule of HCl to the left side of the equation and another molecule of water (H20) to the right side of the equation to give: 

<span>Mg(OH)2 + 2HCl = MgCl2 + 2H20 </span>

The proportion of dissolved substances in seawater is usually expressed in
LiRa [457]

Answer:

The proportion of dissolved substances in seawater is usually expressed in ppm, ppb or ppt

Explanation:

The concentration of very diluted solutions should be expressed in parts per million, billion or trillion.

ppm = mass from the solute . 10⁶ / mass or volume of the solution

ppb = mass from the solute . 10⁹ / mass or volume of the solution

ppt = mass from the solute . 10¹² / mass or volume of the solution

ppm = mg/kg, μg/g, μg/mL → These are the units

ppb = ng/g

ppt = pg/g
