Ch4 draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons.

Solution:- methane molecule has one carbon and four hydrogen atoms, carbon has 4 valence electrons and hydrogen has 1 valence electrons. So, total valence electrons for methane = 4+4(1) = 8

Carbon is the central atom and the four H atoms are bonded to it via single bonds. C uses all it's four valence electrons in bonding. Since total eight electrons are in bonding, the octet of carbon is complete and hence there are no lone pairs.

The lewis structure of methane is shown below:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the answer is a for sure mark brainliest i had got this right on usatestprep
