What is a substance composed of atoms of only one kind?
A chemical element is a substance that contains only one type of atom. The smallest particle of such an element is an atom. Atoms are made up of protons, neutrons, and electrons. Each element contains only one kind of atom. Similarly, is a pure substance composed of atoms of only one kind?
What is an element made of?
Element An element is a pure substance which is made of one type of atom. The atom is distinguished by its atomic number, which is equivalent to the number of the protons located in its nucleus. Every object?solid, liquid or gas?is made of an element or combination of elements.
How many types of atoms are in an element?
An elements is a substance which is made out of atoms that all have the same proton number. So an element can consist of multiple atoms (like oxygen which goes around in pairs). An atom consists of a nucleus and some electrons. Keeping this in consideration, how many different types of atoms are there in a compound?
What is the difference between an element and a substance?
When all atoms that make up a substance are the same, then that substance is an element. Elements are made of only one kind of atom. Because of this, elements are called “pure” substances. A molecule is formed when two or more atoms join together chemically.
What is matter made up of?
Matter is made of atoms. Solids, liquids, gases, and plasma are all matter. When all atoms that make up a substance are the same, then that substance is an element. Elements are made of only one kind of atom.
What is the difference between an element and a compound?
A pure substance is something that occurs in nature. An element is made up of one type of atom only and cannot be split further. A compound has the combined properties of the elements from which it is made. Atoms show the macro properties of an element.
What is an example of pure substance?
Pure Substances are made of the same material throughout and have the same properties throughout. Pure substances cannot be separated into other substances. Some examples are carbon, iron, water, sugar, salt, nitrogen gas, and oxygen gas.
