What is a compound example?
A compound is a material composed of two or more components. Water, carbon dioxide and table salt are some examples of compounds.
What is a compound best definition?
compound. [ kŏm′pound′ ] A substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule. The elements cannot be separated by physical means. Water, for example, is a compound having two hydrogen atoms and one oxygen atom per molecule.
What is compound and element?
Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen.
What are the example of elements?
Common examples of elements are iron, copper, silver, gold, hydrogen, carbon, nitrogen, and oxygen. At present, 94 are natural elements whereas 24 are synthetic. Thus, a total of 118 elements have been identified so far.
What are compounds in simple words?
1) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break.
What is a compound Science 6th grade?
Compound – made up or consisting of two or more existing parts or elements. A compound must have 2 different elements! A molecule is simply 2 bonded atoms.
What are compounds in biology?

What are the types of compounds?
Types of Compounds
- Metal + Nonmetal —> ionic compound (usually)
- Metal + Polyatomic ion —> ionic compound (usually)
- Nonmetal + Nonmetal —> covalent compound (usually)
- Hydrogen + Nonmetal —> covalent compound (usually)
Where can you find metals non metals and noble gases in the periodic table of elements?
Some of the groups have widely-used common names, including the alkali metals (Group 1) and the alkaline earth metals (Group 2) on the far left, and the halogens (Group 17) and the noble gases (Group 18) on the far right. The elements can be broadly divided into metals, nonmetals, and semimetals.
What was the difference between element and compound?
Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.
What is a compound or mixture?
Compound:a substance that is made up of more than one type of atom bonded together. Mixture: a combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.
How do you explain elements to Kids?
A chemical made up of only one kind of atom is called an element. There are 118 different elements, although only 98 of them are found naturally on Earth. Some elements, such as gold, are found in their pure form on Earth. Others, like iron, have to be separated from other substances.
