#electronegative

[tenth-sentence]

A hydrogen bond occurs between a small, highly electronegative atom with a lone pair of electrons and a positively polarised hydrogen atom.

Very important addition to my chemistry notes

Polarization of the Carbonyl Group

-- Carbonyl group:

-- The oxygen has two lone pairs

-- The oxygen is more electronegative than the carbon

-- The polarization arrow will show electrons being pulled toward the oxygen

-- The carbon is partially positive

-- Partially positive = δ+

-- The oxygen is partially negative

-- Partially negative = δ-

-- These symbols go by the arrow

-- The polarization makes the boiling points of aldehydes and ketones higher than hydrocarbons

-- The larger the carbonyl group, the less soluble it is in water

-- If it has more than six carbons, it is insoluble

god i love the idea that bill and the other weirdo monsters couldnt leave gravity falls is because theyre TOO weird yk? like gravity falls attracts weird and theyre so weird that they physically cant leave? love it. eating that shit up

For example, the electron density around the hydrogen atoms in fluoromethane (figure 20.23) is less than that around the hydrogen atoms in chloromethane (figure 20.24), due to the greater electronegativity of fluorine relative to chlorine.

Okay but it's obviously fluorine, right? Most electronegative element. Fluorine's out there getting slutty, serving cunt. Fluorine's reactive, it fucks.

Tumblr staff: ten options is enough for polls, right? No one needs more than that on a regular basis. The average tumblr user: Hey guys which element of the periodic table do you think is the most fuckable?

VSEPR and Molecular Geometry Explained!

Being able to draw Lewis Structures with the correct geometry is the first step in chemistry to being able to understand and explain different properties and behaviors of various molecules. In this video we will cover Valence Shell Electron Pair Repulsion, also known as VSEPR, and how that affects the shapes of different molecules!

What is Electron Affinity? 

Electron affinity refers to the amount of energy released or absorbed when an electron is added to a neutral atom in the gas phase to form a negative ion. Essentially, it measures the tendency of an atom to gain an electron. This property is critical for understanding how atoms become ions and participate in ionic bonding. Enroll now at Tutoroot.

[tenth-sentence]

Substitution at the α-carbon with an atom or a group of atoms of higher electronegativity than carbon increases the acidity of carboxylic acids, often by several orders of magnitude.

found out noble gases can sometimes bond with halogens if the noble gas's pull on their own valence electrons is weak enough and if the halogen's electronegativity is strong enough. That is what resulted in me making this

Hydrogen bonding (Fig. 12.5). A variety of hydrogen-bonding reactions are possible, involving oxygen- and nitrogen-containing functional groups of both the HM and the organic pesticide molecule. In the example shown, the insecticide carbaryl is hydrogen-bonded to HM using the two electronegative atoms, nitrogen and oxygen, in the carbamate structure.

Finished this guy's lil redesign!

My ocs aren't quite spec bio, I don't consider myself smart enough to write the same level everyone in the spec bio community does but alot of people tag my ocs as such, so I decided to entertain a bit and write abit about Q'wilqilth's biology :3

They are basically an overgrown giant bacteria, often referred as "plague angels", the angel part comes from the fact these critters live in a colossal interplanetary organism that many human cultures refer it as the one and true God.

read-

Q'wilqilth-óó is a Neobacteria, often referred generally as 'angels' (though angels include many other non-Neobacteria), Neobacteria are a domain of organisms whose bodies are made up of bacterial colonies acting in tandem as organs, like organs and cells - each colony houses a bacteria with different physiologies to fit a certain role.

And for the same reason, Neobacteria may be composed of species that are pathogenic to humans (hence the 'plague' angel name), they also take on similar mechanisms and ecological roles to their single celled/simple counterparts.

Q'wilqilth in this case (often just shortened to Q'wi) is a Neomyco leprae, derived from the bacteria that causes leprosy in humans, this species is sophont and is often wearing clothing but I decided to add it in there just to see their markings better, they don't have common names and are mostly just referred to as leprosy plague angels, but some species of Neobacteria refer to them as 'Jade emperors' or simply 'Leviathans'

Like many plague angels, this species is a parasitoid/facultative parasite and relies on deploying their genetic material on a host to reproduce, N. leprae prefers doing this to Neural coils, a species derived from Schawnn cells who produce a mucus that stimulates the production of electricity from Neuron trees.

When bursting out of a Neural coil, most will spend years attached to the Neuron trees their former host was attached to, this phase is important to the development of the 'Ouabain whip', a small organ in their tail that helps them regulate their electronegativity and is later used as a weapon, disrupting Na+/K+ ATP-ase in any predators towards them.

They are mostly nomadic, save for a few small tribes/clans, they can travel long distances thanks to their lipid-rich diet, this species has taken lipid/fat as their primary energy source and carbohydrate last, it may not look like but they have extremely mobile/flexible lips and strong toungues/jaws to suck vegetable oil and starch off Neuron trees, unlike their pulmonary counterparts (Tuberculosis), they are facultative aerobics and can use electricity/eletrons provided by the Neuron trees as a substitute for oxygen in ATP production. When migrating out of the Neural forest, they are equipped with mostly molars, strong jaws, and specific digestory enzymes in their mouths to digest tough animal (?) fat. This gives them a much slower metabolism, allowing them to travel without eating for large amounts of time.

Last but not least, though they are gliders, they have evolved their mycolic acid to be hydrophobic in nature, keeping their skin from getting wet/humid, they are great swimmers and their facultative aerobic nature allows them to survive underwater without oxygen, they can live in a variety of biomes within the Super-organism; squashed between arteries close to the red rivers, in the high lands, golden hills or even the filter. They will however, avoid warmer temperatures and prefer sticking to the poles.
