This statement is true. Each element consists of only one type of atom.

Elements consist of only one kind of atom and cannot be decomposed into simpler substances.
Our planet is made up of some 90 elements. (Tiny amounts — sometimes only a few atoms — of additional elements have been made in nuclear physics laboratories, but they play no role in our story). Of these 90, only 25 or so are used to build living things.

The specific heat of gold is 0.031 calories/gram C. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 C, how many calories of heat energy were absorbed by the sample?
Weegy: mc?T = Q. [ m = mass: c = Specific heat capacity: ?T = Change in temp: Q = Heat absorbed. 10g x 0.031cal/g/°C x 20°C ?T = 6.2 calories of heat absorbed. (To change to Joules = 6.2cal x 4.184 J/cal = 26 Joules). ] (More)
