An element is a type of atom, determined by the number of protons that it has (also known as its atomic number). As of 2008, 117 elements have been observed. 94 of these are naturally-occurring on Earth.
The term element does not imply a particular number of atoms, though often it is used to describe a single atom.
Cream is a mixture of milk fat, water, and proteins. These organic compounds contain these elements:carbonhydrogennitrogenoxygenThere may be small quantities of other elements in the proteins.
Water: contains hydrogen and oxygen elements. Table salt: contains sodium and chlorine elements. Aluminum foil: contains aluminum element.
Rocks are usually not elements, but they contain elements.
No, an aqueous solution of a base typically contains hydroxide ions (OH-) along with other cations and anions derived from the base compound dissolved in water. So, it may contain multiple elements, not just two.
Yes it does. Everything in the universe is made up of elements. Elements are a combination of atoms.
No- none of them contain water at all. Water is made up from one hydrogen atom and two oxygen atoms, which are both elements. No element can contain water, as water is made up from elements.
Hurricanes don't contain elements - only water and water vapor.
Hydrogen and oxygen are already elements. Elements do not contain other elements.
Water is a coumpound made up of two elements, hydrogen and oxygen, which makes the most basic unit of water a molecule, not an atom, which is the most basic form of an elements, so no elements contain water.
Well, it depends. There are the elements like mercury and bromine, but they're elements. Other things such as mercury nitrate (Hg2NO3) and potassium chromate (K2CrO4) don't contain water, but they are aqueous solutions.
No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
Typically, a vase would contain flowers, water, and possibly decorative elements like stones or branches.
Water (H2O), carbon dioxide (CO2), table salt (NaCl), and methane (CH4) are examples of compounds that contain two elements.
Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
A molecule contain chemical elements associated by chemical bonds.
H2O, or water, contains two elements - hydrogen and oxygen.
The elements that hydrocarbons contain are: -Hydrogen -Carbons
