The Composition of Rocks: Mineral Crystallinity and Bonding Types

We've been focusing on the layers of the Earth for a while now, so let's start looking at rocks themselves. Rocks are assemblages of minerals. So what's a mineral? What are their properties? What kinds of bonds occur within them? Let's take a look!

"The precise definition of a mineral depends on who you ask" I hear DEA agent Hank Schrader is a good authority on minerals.

Great video, I love how y’all are including chemistry in this. Minerals are such a good, physical example for learners of all ages to conceptualize chemical bonding

[@besotoxicomusic]

I live in the Mojave desert and have a huge collection of rocks I know nothing about. So many of the hippies around here seem to think my collection is vibrant and spiritual but I just think they need to calm down with the hallucinogens and just realize they just look pretty. I’m glad you’re doing this series so I can actually know what I’m looking at.

[@Killbayne]

pretty looking things always have to have a deeper meaning to some people and make their own placebo, but i also just collect rocks because they're pretty. Used to collect tens of glassy sand "lava rocks" that I found on a red sand running field.

What's the purpose for rocks and minerals? I know some can be grinded down to gunpowder, explosive, or salt. After that what are, what are rocks and minerals good for?

[@neharikaduggal1588]

3:27 arent covalent bonds weaker than ionic? In ionic complete tranfer of electron takes place while covalent involves sharing of electron so electrostatic forces will be dominating in ionic bonds

[@LinsonJoseph]

This is what probably Dr. James Tour talks about Dave having some good videos too.

Aren't ionic bonds typically stronger than covalent bonds?

[@marknieuweboer8099]

No.

[@jagmeemees]

@@marknieuweboer8099 I recall that my gen chem course in university mentioned this and all sources I can find with a quick google search agree with me. Please elaborate if you can.

[@WanderTheNomad]

@@jagmeemees Here's one answer I found on quora: "What bond is stronger, covalent or ionic?" "There is no general answer to your question. Some ionic bonds are stronger and some covalent bonds are stronger. • lonic bonds are stronger than covalent bonds in vacuum (vacuum is a space in which there is no matter including air). • In biological conditions (e.g. : living cells) which are often aqueous (involves water) covalent bonds are stronger than ionic bonds. Why? because water dissociate ionic compounds (e.g.: dissociation of salt in water)."

[@marknieuweboer8099]

Interestingly I found sources that contradict each other. I'll give you my first impression; right now I don't have the time to check carefully. It seems to matter if we're talking molecules or the atoms a single molecule consists of. Groups of molecules with ionic bonds are stronger, in the sense that more force is needed to tear them apart. But it takes more force to pull a molecule with a covalent bond apart than to do it with a molecule with atoms apart. The atoms of table salt will roam freely in water when you put them into that. The atoms of oxygen won't. So I change my previous answer: it depends on your criterium. Thanks, I like this.

[@anastasiailieva7800]

Please elucidate us on the reasons/ proof that crystal growth does not occur due to some inherent proto-intelligence on sub-atomic energy level. How about autocatalysis? tnk you.

[@ProfessorDaveExplains]

Autocatalysis? Crystal growth is not a chemical reaction.

[@anastasiailieva7800]

@@ProfessorDaveExplains I did not say that. My question is why any of these phenomena (that exhibit some ' innately driven' growth/movement/spatial arrangement like crystal growth, chemical autocatalysis, spontaneous folding of proteins, etc) cannot be explained by the presence of some inherent proto-intelligence on a very subtle level. thnk you.

[@HardToBeAPoopGod]

"they're not rocks, marie. they're minerals"

[@RicardoMorenoAlmeida]

Uh, steps 3 and 4 of the criteria for mineral status are totally meaningless. Excluding energy or subatomic particles, anything we're in contact with is composed of elements or compounds and can be characterized by a chemical formula. That is akin to saying anything in chemistry is a chemical. Anyone in disagreement, please show me something on Earth (again, excluding energy or subatomic particles) that does not fit those two criteria.

[@ProfessorDaveExplains]

No, not everything can be characterized by a chemical formula. We are talking about a repeating formula unit. Things that aren't crystalline don't have that.

@@tyton3 I am inclined to believe the story of Jesus was possibly based in the beginning on a preacher who was executed, although the details , even his name , are suspiciously similar to other myths within the pagan culture at the time. His date of birth, virgin mother the Sun or Son all can be found in several pagan pantheons.
