There are a lot of substances that are made up of the same elements. I am not quite sure if you meant the exact same elements, like only those, and no others, or if you meant some substances that are made out of the same elements, but others can be added:
Scenario 1:
Oxygen: O, O2, O3
Carbon: CO CO2
Scenario 2:
H, H2, HCl,
K, KNO3
H2O, H3O
No, substances can be elements or compounds. Elements are pure substances made up of only one type of atom, while compounds are made up of two or more different types of atoms chemically bonded together.
substances
They are alike because some are made out of the same elements.
They are all Elements and They are diiferent substances
air, water
The elements of a compound are the simplest components that it can be broken down into by chemical means. The atoms of an element have the same number of protons and electrons and have the same behaviors.
Mainly Carbon And Some Other Elements
Heating an element can cause it to change physical form, but it will not break down into simpler substances. Elements are made up of only one type of atom and cannot be decomposed further by heat alone.
A non-example of an element is something that is made up of elements but isn't actually an element. Some examples are water, salt, brass, and steel.
The fingernails are made of hardened cells of the epidermis, your outer skin layer. The cells have keratinized into a hardened, scalelike covering to protect the tips of your fingers, and the edges help you to pick up small objects.
Predominantly, yes; both are carbon, with some possible impurities.
The properties of a subtance depend not only on the atoms/elements it contains, but also the bonding patterns between them. In some cases, ie hydrogen peroxide and water, different bonds exist in one material which gives it different properties, such as the oxygen-oxygen peroxide bond. In other materials such as diamond and graphite, the same atoms are bonded together (in this example, carbon), but the crystal structure is different, thereby conveying vastly different properties to substances that seem similar. Thus, due to different atoms bonding and changes in crystal structure, many compounds can be formed from only a few elements.
