Yes it does, its derived from the greek name for beryl, or beryllo
Answer:
3,4,5,6,7,8
Explanation:
Groups 13 - 18 are the main group on the periodic table
The group number corresponds the number of valence electrons they contains.
Valence electrons are the number of electrons in the outermost shell of an atom.
So group 13 - 18 corresponds to a valency of 3,4,5,6,7,8.
Groups with a valency of 8 are the noble gases.
There are three kinds of Hydrogen in 2-methyl-2-butene
The correct question is
How many kinds of hydrogen atoms are present in 2-methyl-2-butene
<h3>What is an atom ?</h3>
Atom was discovered by Dalton's Atomic theory , he predicted that each element consist of large number of a very small thing known as atom.
In the structure of 2-methyl-2-butene there are 3 types oh Hydrogen
1. Attached to the Carbon atom connecting the methyl ion to the butene
2. Connected to the last Carbon atom
3. Connected to the Carbon bond having double bond.
Therefore there are three kinds of Hydrogen in 2-methyl-2-butene.

An Arrhenius base<span> is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution. I believe the correct answer from the choices listed above is option A. The reaction that </span>displays an example of an Arrhenius base would be <span>NaOH(s) --> Na+(aq) + OH–(aq). Hope this answers the question.</span>
The electromagnetic force is responsible for the electrostatic attraction and repulsion between charged particles and since the protons have positive charge and electrons have negative charge so the electromagnetic force will be the fundamental force primarily responsible for the attraction between electrons and protons
