What are elements and compounds answer key?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What are the elements compounds and mixtures?
What is the difference between an element a compound and a mixture? A material that only consists of one form of atom. Compound: A material which consists of more than one form of bonded atom. Mixture: a blend of two or more unbounded components or compounds; each component of the mixture preserves its own properties.

Are compounds composed of elements that join in a specific ratio according to their masses?
A compound is a pure substance composed of two or more elements that are chemically combined. Elements combine by reacting with one another. A particle of a compound is a called a molecule. Elements join in a specific ratio according to their masses to form a compound.
What is mixture in chemistry?
A mixture is made when two or more substances are combined, but they are not combined chemically. General properties of a mixture: ● The components of a mixture can be easily separated. ● The components each keep their original properties.
What is a compound mixture and element example?
An example of a compound is table-salt. It is a compound because it is made up of two different types of atom – in this case sodium and chlorine….Chemistry: 12. Elements, Compounds and Mixtures.

What are elements compounds and mixtures for kids?
Elements, Compounds, and Mixtures
- A sample of a pure element contains atoms that are chemically the same, but different from those of all other elements.
- Compounds are formed by a process called a chemical reaction.
- Substances such as milk, paint, ink, air, and muddy water are mixtures, as are rocks and metal alloys.
Is a pizza an element compound or mixture?
Yes, pizza is a mixture. This is because the components of pizza (dough, sauce, cheese, toppings) are not chemically bonded to each other, and can easily be separated.
Is chocolate sundae a mixture?
Homogeneous is a mixture where components are equally or uniformly distributed and the composition remain same throughout the mixture. The mixture can not be separated. (b) chocolate sundae. It is a heterogeneous mixture.
When elements mix in any ratio they form a?
A compound consists of atoms of two or more elements combined in a small, whole-number ratio. In a given compound, the numbers of atoms of each of its elements are always present in the same ratio (Figure 2).
How is a compound different from a 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.
Is matter an element or compound?
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. Because of this, elements are called “pure” substances.
Do homogeneous mixtures contain elements?
A homogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components cannot be visually distinguished. Often separating the components of a homogeneous mixture is more challenging than separating the components of a heterogeneous mixture.
Are compounds a mixture?
Compounds are substances which are pure in every way. The mixture is a substance which is always impure. Compounds are two or more substances which are mixed together with the help of a chemical reaction while the mixture is two or more substances which are mixed together with the support of a physical process.
How are compounds and mixtures similar?
Compounds are pure substances. They are made from the same types of molecules. Each molecule of a compound is made from two or more different kinds of atoms that are chemically bonded. Mixtures are made of two or more substances — elements or compounds — that are mixed physically but not chemically; they do not contain any atomic bonds.
