What is Brinklehoff?

"Brinklehoff" most commonly refers to a mnemonic device, BrINClHOF, used in chemistry to remember the seven diatomic elements (Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, Fluorine) by sounding like a name, or to Robert Brinkerhoff's influential Success Case Method for evaluating training and organizational change, which identifies best and worst examples to understand program effectiveness. It can also refer to the prominent Brinkerhoff family or various places named after them, like Brinckerhoff, NY, notes this Wikipedia page.

What is special about BrINClHOF?

1 : The element symbols for Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen and Fluorine spelling out "BrINClHOF" a handy mneumonic for memorizing the diatomic elements.

What is diatomic in simple words?

The best definition of a diatomic molecule is two atoms of the same or different elements that are chemically bonded together. Diatomic molecules consist of only two atoms.

Has element 119 been found?

Neither element 119 nor element 120 was observed. The experiment was originally planned to continue to November 2012, but was stopped early to make use of the 249Bk target to confirm the synthesis of tennessine (thus changing the projectile to 48Ca).

What's so special about bromine?

35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.

Brinkerhoff - an alternative to Kirkpatrick for training evaluation

Is bromine toxic to humans?

Mechanism of Toxicity. Bromine, a strong oxidizing agent, is a respiratory irritant and can cause pulmonary edema in humans and animals (Teitelbaum 2001). Reaction with water results in the formation of hypobromous acid, HOBr, which slowly decomposes to hydrobromic acid and oxygen (Downs and Adams 1973).

What food is high in bromine?

Bromine is found, on average, in the highest concentration within a few different foods, such as brazil nuts (Bertholletia excelsa), yellow bell peppers (Capsicum annuum), and red bell peppers (Capsicum annuum) and in a lower concentration in horseradishes (Armoracia rusticana), mandarin orange (clementine, tangerine), ...

What is the rarest element on Earth?

Astatine. Astatine is a chemical element; it has symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements.

How long would element 119 last?

Any atom of element 119 or 120 will likely last only a few milliseconds before emitting bundles of protons and neutrons and decaying to lighter elements. Such a fragile and fleeting entity is unlikely to be practically useful.

What element will we run out of first?

Currently, helium is the element most likely to run out. Gases such as nitrogen, hydrogen and oxygen are easy enough to obtain – we can extract nitrogen from air and use electrolysis to split water to obtain hydrogen and oxygen. But the same isn't true for helium. This gas is produced in small amounts deep underground.

What are 7 diatomics?

The 7 diatomic elements are hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).

What are the three triatomic elements you know?

Triatomic molecules are molecules composed of three atoms, of either the same or different chemical elements. Examples include H2O, CO2 (pictured), HCN, O3 (ozone) and NO2.

Why is oxygen known as diatomic?

In order to achieve the octet configuration, they share their unpaired electron with the unpaired electron of another element and result in a diatomic molecule. By achieving octet configuration, the diatomic elements become more stable compared to the single atom. Therefore, oxygen and hydrogen are diatomic.

What is the rule of 7 in chemistry?

The "rule of 7" in chemistry usually refers to the seven diatomic elements (H, N, O, F, Cl, Br, I), often remembered with mnemonics like "Have No Fear Of Ice Cold Beer," which are elements that exist as two atoms bonded together in their elemental form. It can also loosely relate to Group 17 elements (halogens) having seven valence electrons, needing one more to complete their octet (8 electrons) for stability, which is central to the octet rule and chemical bonding.
 

What does bromine smell like?

Bromine has a sharp, pungent, irritating odor often described as similar to bleach, chlorine, or even vomit, sometimes with a slightly sweeter or metallic hint, but it's distinct and unpleasant, stemming from its Greek root meaning "stench". While elemental bromine fumes are very potent, the smell in hot tubs comes from its reaction byproducts (bromamines), which people sometimes mistake for excessive chlorine smell, though it's less harsh than chloramines. 

Could element 200 exist?

There are some "islands of relative stability", where heavy elements are stabilized by "magic numbers" of protons and neutrons -- which is why thorium and uranium are so long lived. But we can be quite certain that there is no such thing as Element 200.

What is the newest element?

The newest officially recognized elements are Nihonium (Nh, 113), Moscovium (Mc, 115), Tennessine (Ts, 117), and Oganesson (Og, 118), added in 2016, completing the seventh row of the periodic table; however, scientists are actively searching for Element 119 (Ununennium), which would start the eighth row and be the next addition. 

Is there a 120th element?

Unbinilium, also known as eka-radium or element 120, is a hypothetical chemical element; it has symbol Ubn and atomic number 120.

What is the #1 element found on earth?

Oxygen is by far the most abundant element in the Earth's crust, making up 46% of mass—coming up just short of half of the total.

Can I eat astatine?

Astatine has no known biological role. It is toxic due to its radioactivity.

What is the rarest natural thing on earth?

Astatine probably tops the charts as the rarest element, with only 1 gram thought to be present on Earth at any given time, and only 0.05 micrograms have even been created.

Is there bromine in Coca-Cola?

No, Coke doesn't contain brominated vegetable oil, according to Coca-Cola.com. And no, Mountain Dew does not have BVO in its ingredients list, according its maker, PepsiCo. In fact, PepsiCo and Coca-Cola no longer use BVO in any of their products, NBC News reported. Gatorade also no longer contains BVO, Hansen says.

Why is bromine banned?

Bromine exposure has been linked to thyroid dysfunction, memory loss and skin problems in animal studies. Though no human health effects at current levels of exposure have been identified, the FDA said there was enough uncertainty to warrant action. The bromines are stored in heart, liver and fat tissue.

What replaced iodine in bread?

In 1980, iodine was removed from bread and was replaced by bromide. This was highly unfortunate, as bromide is toxic.
