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:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
