Not at all. The little numbers after the element's chemical symbol show you how many atoms of that element the compound has. For example, CH4 is methane, C2H6 is ethane, which would have 8 atoms instead of methane's 5, C3H8 is propane with 11 atoms, as long as hydrocarbons are concerned. But there are compounds such as proteins with hundreds of atoms and there their arrangement in space makes a lot of difference for their chemical and physiological properties.
A compound is a substance made up of two or more different types of atoms that are chemically bonded together. These atoms can be from different elements or the same element. The properties of a compound are different from the properties of the individual elements that make it up.
Atoms in a compound are chemically bonded together in specific arrangements. The atoms can be the same element (in a molecule like O2) or different elements (in a compound like H2O). The combination of atoms in a compound determines its unique properties and chemical behavior.
False. A compound exhibits properties that are different from the elements that formed it due to the new chemical bonds and interactions between atoms in the compound.
Yes, atoms make up almost everything, they can only be broken down into protons, neutrons and electrons. An element is a substance found on the periodic table with certain rules and regulations given to each element. An element is made up only of atoms. A compound is a mixture of two or more elements that can be broken down into elements again, it is not a pure substance as such. So a compound is made up of elements, elements are made of atoms.
It is usually a compound- several elements
Isotopes are atoms of the same elements with different number of neutrons.
Elements are made of atoms. Each element is made up of the same kind of atoms, having the same atomic number.
no
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
Today this affirmation is not generally valid.
no
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance, it is a compound. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
shells
A compound is a substance made up of two or more different types of atoms that are chemically bonded together. These atoms can be from different elements or the same element. The properties of a compound are different from the properties of the individual elements that make it up.
Such atoms belong to a group in the periodic table of elements.
Subscripts in a chemical formula are whole numbers because they represent the ratio of atoms in a compound. They indicate the number of atoms of each element present in the compound in the simplest whole number ratio. This is based on the law of constant composition, which states that a compound always contains the same elements in the same proportion by mass.
That's because of the way "compound" is defined. If atoms of an element combine with other atoms of the SAME element, then it's not called a "compound".
