The first person to discover a Periodic Table was Dmitry Mendeleyev, a Russian chemist founded the periodic table in 1869.
Dmitri Mendeleev, considering he created it.
Answer:
In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

Fluorine in compounds is always assigned an oxidation number of -1
Answer:
The correct answer is option A.
Explanation:
Stars are bundles of hot gases which primarily consists of hydrogen gas and then helium. Their shine is due to thermonuclear fusion of hydrogen into helium or burning of hydrogen gas into helium in their cores which releases large amount of energy and later this process leads to formation of some heavier elements.
Answer:
p-bromobenzyl cyanide
Explanation:
In a nucleophilic substitution, a nucleophile replaces a leaving group (halide ion) from a carbon atom, using a lone pair of electrons to form a new bond with the carbon atom.
In this reaction, the <u>cyanide ion is the nucleophile</u> and the <u>bromide ion is the leaving group.</u>
This nucleophilic substitution is an example of an SN₂ reaction. This reaction occurs in a single step, where <u>bonds break and form simultaneously.</u>
In this product, the nucleophile occupies the opposite stereochemical position to the original position of the leaving group. This result is known as an inversion of the carbon atom configuration.
