What is a reactive molecule?
A type of unstable molecule that contains oxygen and that easily reacts with other molecules in a cell. A build up of reactive oxygen species in cells may cause damage to DNA, RNA, and proteins, and may cause cell death. Reactive oxygen species are free radicals. Also called oxygen radical.
Which is highly reactive atom or molecule?
Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.
Which is highly reactive compound?
Examples of highly reactive chemicals are explosives, peroxides, water-reactives, and pyrophorics. All work involving highly reactive chemicals should be approved by the laboratory supervisor before initiation of the work.
What is highly reactive?
The halogens, alkali metals, and alkaline earth metals are highly reactive. The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element). The least reactive elements are the noble gases.
How do you tell which molecule is the most reactive?
The elements that are the most reactive on the periodic table should be located to the upper right hand corner of the table – these elements are the most electronegative.
Is chlorine highly reactive?
Halogens are notorious electron-hogs; powerfully attracting electrons from atoms of other elements, particularly from the alkali metals. This makes the halogens highly reactive. Chlorine, being one of the smaller halogens, will react strongly with most elements.
Why are halogens highly reactive?
Halogens are nonmetals in group 17 (or VII) of the periodic table. Due to their high effective nuclear charge, halogens are highly electronegative. Therefore, they are highly reactive and can gain an electron through reaction with other elements.
Which are the highly reactive metals?
– So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.
Is sodium highly reactive?
Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium.
Is Neon highly reactive?
Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).
Why are some molecules more reactive?
The CH4 molecule has four bonds to C, which is typical of a neutral group 14 compound. The carbon atom has no lone pairs to share and no tendency to gain electrons, and each hydrogen atom forms one bond that contains two valence electrons. Thus CH4 is neither an electrophile nor a nucleophile.
