Answer:
Ionic bonding: C
Covalent bonding: B
Metallic bonding: D
Pauli exclusion principle: A
Explanation:
All the electrons in 1 atom are characterized by a series of 4 numbers, known as quantum numbers. These numbers (n, l, ml, ms) describe the state of each electron (in which level, sublevel, orbital it is and its spin). For 2 electrons to coexist in the same atom they must differ in at least of these numbers. If they occupy the same level, sublevel and orbital, then they must have different (and opposite) spins. This is known as Pauli exclusion principle.
Also, to gain stability atoms can gain, lose or share electrons. In doing so they form bonds. There are 3 kinds of bonds:
- Ionic bonding: these are formed between metals and nonmetals. Metals tend to lose electrons and form cations (positive ions) and nonmetals tend to gain electrons and form anions (negative ions). Cations and anions attract each other due to <em>electrostatic forces</em> between <em>oppositely charged ions</em>.
- Covalent bonding: these are formed between nonmetals, which share pairs of electrons so as to reach the <em>electron configuration</em> of the closest noble gas (the most stable electron configuration).
- Metallic bonding: valence electrons are loose in metals, so they move together as a "sea of electrons", acting as <em>"glue"</em> of the remaining positive <em>cores</em> (electrons that are negative charges serve to attract the positive charges of the cores).
Answer:
The power of yet is a way to change you mindset about something. It gives you a positive mindset, because it you say I cant do this yet. you are not giving up

I hope this helped you! Brainliest would be greatly appreciated.
In my opinion I believe it would be motion because depending on how fast the person is going it would determine the outcome of the race
<em>V= 110mL = 110cm³ = 0,11dm³</em>
<em>C = 1,244 mol/L = 1,244 mol/dm³</em>
C = n/V
n = 1,244×0,11
<u>n = 0,13684 moles</u>
<em>mCa(OH)₂ = 74 g/mol</em>
1 mole Ca(OH)₂ ------------ 74g
0,13684 ---------------------- X
X = 74×0,13684
<u>X = 10,12616g</u>
