In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gasses, they are spread out. Particles in chemistry can be atoms, ions or molecules. And remember, it is important to understand the particle nature of matter
Answer:
Explanation:
A = A metal that lost three electrons is Z³⁺
Metals loses their electrons and form cations. So when an metal loses three electrons positive three charge is created.
B= A metal that lost one electrons is Y⁺
When metal loses one electron positive one charge is created.
C=A nonmetal that gained one electrons is X⁻
When non metals gain the electrons anions are formed and negative charge is created on atom due to addition of electron. So when non metal gained one electron -1 charge is created.
D= A nonmetal that gained three electrons is V³⁻.
when non metal gained three electrons -3 charge is created, because of addition of three electrons.
Answer:- none
Explanations:- For naming hydrocarbons we use the suffix -ane, -ene and -yne.
-ane is used when we have only single bonds between all carbons. -ene is used if there is any double bond between two carbons and the -yne is used if there is any triple bond between two carbons.
The given name of the compound is propane. It ends at -ane and so it's an alkane and must have single bonds between all the carbons it has. So, there are zero double bonds present in .
This is also clear from the below lewis dot structure of the compound.
4.5 x 10-4
An easy trick is to count the zeros.
I think the particle starts to move slowly around because no heat or pressure is applied to it
