<span>Planck’s constant relates the
joules of energy absorbed/released by matter to the wave frequency f. the
plancks constant was first recognized in 1900 by Max Planck. The equation that
relates the joules of energy absorbed/released by matter to the wave frequency
f is called the plancks-eintein relation, E = hf</span>
The cell walls are different, plant cells require more rigidity. that's all I know
One oxygen atom shares two electron with two hydrogen atoms in this way water molecules are formed. The bond between oxygen and hydrogen is covalent bond.
<h3>What is covalent bond ?</h3>
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. Bonding pairs or sharing pairs are the names given to these electron pairs.
Covalent bonding is the stable equilibrium of the attractive and repulsive forces between atoms when they share electrons.
According to the amount of shared electron pairs, there are three different forms of covalent bonds. single covalent bond is one type of covalent bond. covalent double bond and covalent triple bond.
Thus, option B is correct .
