Are made of 2 or more kinds of atoms chemically combined in a certain ratio?
compound
A compound is a pure substance made of two or more elements chemically combined in a set ratio. A compound may be represented by a chemical formula, which shows the elements in the compound and the ratio of atoms, CO2.
What has two or more atoms bonded together?
When two or more atoms chemically bond with each other, the resultant chemical structure is a molecule. Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed.
Can a compound contain more than one type of atom?
A compound must contain more than one type of atom, and a molecule can be two or more of the same type of atom. Why can a compound be a molecule, but a molecule cannot always be a compound? physically A mixture is when two or more elements combine how to separate a mixture.
What do you call elements that are chemically combined in a definite ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
Which is a compound composed of two or different elements?
A compound is a pure substance, composed of two or more elements chemically combined, and having a definite proportion. Water, H2O, is a compound of hydrogen and oxygen; carbon dioxide, CO2, is a compound of carbon and oxygen; and glucose, C6H12O6, is a compound of carbon, hydrogen, and oxygen.
Which is a pure substance composed of all the same kind of atoms?
A pure substance is an element or a compound. In the case of an element, it is composed of all the same kind of atoms. In the case of a compound, the atoms of the elements are chemically bonded in definite proportions, meaning that all samples of the same compound are chemically the samel.
