A period is horizontal; the elements gain 1 proton for each space moving left to right.
A group is vertical; the elements in each group have the same number of electrons in the valence shell(outer orbital).
The volume will decrease, because as the temperature is lowered, the atoms will move slowler and they won't fill as much the balloon
Assuming the planets orbit is in the Goldilocks zone (the distance from the star where the temperature is just right), if the orbit was too irregular or elliptical, the planet would fly out too far to where it is too cold to maintain life and sustain liquid water, and the planet would fly too close to the star making it too hot and unable to support life.
Answer:
of equal length and are midway between a single bond and a double bond
Explanation:
Benzene -
The chemical formula for benzene is C₆H₆ , which consists six bonds , which are of each bond length , which is somewhere in between double and single bond .
The property responsible for this type of bond length in benzene molecule is Resonance .
Resonance refers to the process of delocalization of electron in the given structure .
Hence , from the given question ,
Due to the process of resonance , the bond length between the carbon and hydrogen is of equal length .
A molecular structure also shows the bond angle and the Bond length between different atoms in a compound.
