Carbon and Oxygen can for Carbon Monoxide (CO), Carbon Dioxide (CO2), Carbon Trioxide (CO3), etc.
A melting point of over 700 C and a density of less than 2 g/cm3 can be observed for many group 2 elements. In this group, the density increases on moving down the group, whereas the melting point increases upto calcium and then starts decreasing.
Calcium, symbol Ca is the element with melting point around 840 C and density of 1.55 g/cm3 which is closest to the specified data range .
