All matter is made up of various elements in a pure form, or are part of compounds or mixtures.
A mixture consists of two or more substances mechanically mixed together in any proportion and without chemical bonding between the different substances.
A compound is a substance formed by chemical union of two or more elements or molecules in definite proportion by weight.
An element is a pure substance that cannot be separated into a simpler substance.
An element contain atoms with the same number of protons.
A compound contain two or more elements associated by chemical bonding.

What is the difference between a compound and hydrogen?
A compound is a combination of at least 2 different elements or ions, while Hydrogen is simply an element.
What is the different between the chemical name and the chemical formula for a compound?
The chemical name refers to the full name of a compound, while the chemical formula represents the composition of elements in that compound using symbols and subscripts. The chemical formula provides information about the elements and their ratios in the compound, while the chemical name typically includes the names of the elements and possibly other descriptive terms.
What is similar elements located next to one another anywhere on the periodic table?
The difference in atomic number between adjacent elements is always one (1).
Why rubber have the same empirical formula as its monomer?
An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
When elements chemically bond together they make a?
compound. A compound is a substance formed when two or more elements are chemically bonded together in specific ratios.
What is the diffrance between a element and a compound?
a compound is a mixture of elements. that is the difference
Is the properties of a compound are very similar to its elements?
true
Why is it important to recognize the difference between elements and compound?
glass
What is the difference of elements to compound?
elements are that they are only made up of one type of atom and a compound is chemically bonded together with differents substances.
What are difference between element mixture and compound?
A compound contain elements chemically bonded.A mixture contain two or more compounds; they can be separated by physical procedures.An element is formed only from similar atoms, having the same number of protons.
What is the difference between a mixturre and a compound?
A mixture is a collection of various elements which have not ionically bonded. A compound is when those elements are heated up and join together. Mixture = Iron and Sulphur Compound = Iron Sulphate
How do you predict if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table?
Predicting if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table involves comparing their electronegativities. If the electronegativities of the atoms are similar, the bond is nonpolar. If there is a significant electronegativity difference between the atoms, the bond is polar.
Which property is the best indicator that a compound may be ionic?
The large difference in electronegativity between the elements in the compound is the best indicator that a compound may be ionic. Ionic compounds typically form between elements with a large electronegativity difference, resulting in the transfer of electrons from one element to another.
What is the difference between a compound and hydrogen?
A compound is a combination of at least 2 different elements or ions, while Hydrogen is simply an element.
Is the properties of a compound very similar to its elements?
The properties of a compound are usually different from those of its individual elements because chemical bonds are formed between the elements, leading to new chemical and physical properties. These properties are determined by the arrangement of atoms in the compound, as well as the type of bonds that are formed.
Difference from mixture and a compound?
A compound is formed from chemical elements bobded by chemical bonds.A mixture contain two or more compounds which can be separated.
What test is commonly used to determine if a compound is ionic or covalent?
The electronegativity difference between the elements in the compound is commonly used to determine if a compound is ionic or covalent. If the electronegativity difference is large (typically greater than 1.7), the compound is likely ionic; if the difference is small (around 0.5 or less), the compound is likely covalent.
