Is a sample composed of atoms only having the same atomic number an isomer?
No. (Element is the word you're looking for.)
Why is a sample of matter considered a pure substance?
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
Why may a geologist have to break a mineral sample to determine its true color?
Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.
What is a sample of a colloid?
sample of colloid?
A sample is composed completely of gold absolutely free of impurities Which term or terms could be used to describe this sample?
element, pure substance
What color is the lithosphere?
It depends. A sample from the crust could be a wide variety of colors. A sample of rock from the lithospheric mantle would be green, as it is composed mostly of peridotite.
Is argon made of molecules?

The steel (solute) is being dissolved into the iron (solvent)
What is the sample in the study of cell phone and passenger conversation in simulated driving?
The sample in the study likely consists of individuals who are using a cell phone or engaging in conversation as passengers in a simulated driving environment. This group would be studied to understand the impact of these distractions on driving performance and safety.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
