Hexane is '6' carbon atoms. As per the IUPAC noimclature (naming system). The number of carbons goes by the following names. #1 ; meth ; methane (CH4) # 2 ; eth ; Ethene (H2C=CH2) #3 ; prop ; Propyne (CH3-C///CH) #4 ; but ; butane (CH3CH2CH2CH3) #5 ; pent ; pentane (CH3CH2CH2CH2CH3) #6 ; hex ; hexane (CH3CH2CH2CH2CH2CH3) #7 ; hept ; heptane (CH3(CH2)5CH3) #8 ; oct ; Octane (CH3(CH2)6CH3) #9; non ; nonane (CH3(CH2)7CH3) #10 ' dec ; decane (CH3(CH2)8CH3) The naming system does go on , but these are the first ten names. This nomenclature is based on Latin numers. Depending on the functional group present, the suffixes are -ane(alkane), -ene(alkene) and -yne(alkyne) Note the one letter difference in the functional group name for 'a', 'e' amd 'y'.
Hept stands for seven and there are seven carbon atoms in heptyl group.
The seven energy levels that are known to exist can hold a total of 118 electrons. In order from one to seven, they are 2, 8, 18, 32, 32, 18, and 8.
Hept = seven. So 7 carbons are found in each molecule of heptane.
The menorah
Heptagon: an enclosed plane area, bounded by seven straight sides.Heptathlon: a competition comprising seven athletic events. Heptane: a linear hydrocarbon with 7 carbon and 16 hydrogen atoms.
the Menorah
menorah (×ž× ×•×¨×”)
The Menorah - The menorah is the oldest symbol of the Jewish faith. It is the seven branched candelabra that stood in the Temple.
It sounds like you are talking about the menorah (×ž× ×•×¨×”) which is a seven-branched candelabra and the traditional symbol of Israel.

It refers to the flame of the golden seven-branched olive oil menorah (candelabrum) in the Sanctuary.
It is called a Menorah. It has seven candles because that was the number of oil lamps on the menorah in the Holy Temple (Exodus ch.25). The Hanukkah-menorah has eight candles because that was the number of days of the miracle with the oil.
A volatile, colorless, highly flammable liquid hydrocarbon, C7H16, obtained in the fractional distillation of petroleum and used as a standard in determining octane ratings, as an anesthetic, and as a solvent.
There are two types of menorah: the Temple one, which was a seven-branched gold candelabrum (Exodus ch.25); and the Hanukkah one, which is a nine-branched candelabrum. Many Hanukkah candelabra are gold in color, but they can be whatever color you choose.See also:More about Hanukkah
