Pentyne is an alkyne with five carbon atoms in its longest carbon chain. The molecular formula for pentyne is C5H8, indicating that it contains five carbon atoms. There are two isomers of pentyne: 1-pentyne and 2-pentyne, both of which have the same number of carbon atoms.
The "pent" is the clue here. That means 5 carbon atoms.
In the IUPAC nomenclature (naming system), they fall back on Latin numeration. 'Pent' in the name means five(5) , so there ate five atoms of carbon . Correspondingly , the '-yne' means there is a TRIPLE bonded pair of carbons. The '1' indicates the position of the carbon at the start of the triple bond. So 1-pentyne is structured.

Pentyne is CHCCH2CH2CH3. This compound has 8 hydrogen atoms.
The line-angle diagram for 2-pentyne represents the structure of the molecule using lines to depict bonds between carbon atoms. In this diagram, the carbon backbone consists of five carbon atoms with a triple bond between the second and third carbon atoms, indicating it is an alkyne. Each vertex or end of a line represents a carbon atom, and hydrogen atoms are implied to be attached to the carbon atoms to satisfy their tetravalence. Therefore, the line-angle diagram visually simplifies the molecular structure while highlighting the triple bond characteristic of 2-pentyne.
