It is an element
A molecule made up of two or more different elements is called a compound, whereas a molecule made up of two of the same elements is still just an element.
A substance in which all the atoms are the same is called an "element".
Fungal cell walls are made of chitin the same substance that insect and crustacean exoskeleton are made of. Chitin is a polysaccharide a long chain of sugar molecules.
Elements and atoms are mainly the same. Molecules are made up of atoms and chemical bonds are bonds that combine the atoms together to make molecules. Compounds are just about the same as molecules only are made up of molecules like how molecules are made of atoms. Substances can relate to anything, and mixtures are many compounds and molecules mixed together.
It is intermolecular force of attraction, it may be 1- dipole - dipole interaction, 2- vander waal's force of attraction.
Cohesion is the force of attraction between molecules of the same substance which binds the particles together.
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
If all of the molecules of the substance are the same molecule
If all of the molecules of the substance are the same molecule
iam vipin das from kerala.................................................. i think the force of attraction between same substance is more power than force of attraction between different substance ,i prooves this based on some experiments here the newtons law of gravitation is falsifyed, for more details condact me 9947410345
a pure substance is that which contains same atoms or same molecules..
It is called keratin, and it's the same protein that hair, and horns are made out of.
A molecule made up of two or more different elements is called a compound, whereas a molecule made up of two of the same elements is still just an element.
A substance in which all the atoms are the same is called an "element".
Generally, the molecules in gases are further apart than molecules of the same substance in either liquid or solid state. However, note the existence of a critical temperature for each substance. Above the critical temperature, no liquid or solid phase can exist, but it would be theoretically possible to compress a supercritical substance so that it would have closer molecules than some liquid form of the same substance.
Fungal cell walls are made of chitin the same substance that insect and crustacean exoskeleton are made of. Chitin is a polysaccharide a long chain of sugar molecules.
diamond is the hardest substance known to science at this time, and graphite is a rather weak substance, and they are both made of the same elements. Their only differences are the arrangement of the molecules
