What happens to atoms when chemical reaction occurs?
An atom is a particle which makes up an element. When an atom reacts with another atom, they create a chemical bond. When this happens, the elements made from these atoms make a compound. Example: 2 Hydrogen atoms + 1 Oxygen atom ---> water (H2O)
Can an element be broken down in a simpler substance?
In a word, no.
What particles make up elements and compounds?
Elements are made up of atoms, which consist of protons, neutrons, and electrons. Compounds are made up of molecules, which are formed when two or more different types of atoms are chemically bonded together.
What is a formed or broken apart during a chemical reaction?
Chemical bonds are formed or broken apart during a chemical reaction. Bonds between atoms are either created or destroyed, resulting in the formation of new compounds or the breakdown of existing ones.
When two atoms of the element oxygen combine to form a molecule of oxygen the result is not a compound Why?
When two atoms of the element oxygen combine to form a molecule of oxygen (O2), it is still considered a pure substance because both atoms are of the same element. A compound is formed when atoms of different elements bond together. In this case, O2 is a molecule of an element rather than a compound because it consists of two atoms of the same element bonded together.
What the elements formed after atoms have broken down and reformed?
radioactive decay
The elements formed after atoms have broken down and reformed are said to be?
The elements formed after atoms have broken down and reformed are known as isotopes. Isotopes have the same number of protons but a different number of neutrons in their nucleus, leading to variations in atomic mass.
What is formed or broken in a chemical reaction?
Some bonds between atoms are broken and new bonds are formed.
When bonds between atoms are broken or formed is the outcome A a physical change B an element increasing in size C a chemical change D a change of state?
C. a chemical change. When bonds between atoms are broken or formed, it involves a rearrangement of the atoms and results in the formation of new substances with different chemical properties. This is characteristic of a chemical change.
What is created when chemicals reactions join atoms together?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
What is created when chemicals reactions jion atoms togethter?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
The basic particle from which all elments are mad is a molecule?
An element is formed from atoms; atoms are formed from protons, neutrons and electrons.Protons and neutroms are formed from quarks and gluons.A molecule is formed fro atoms.
What makes a compound and an element?
A chemical compound is formed from chemical elements.A chemical element is formed from atoms; atoms contain an atomic nucleus (protons and neutrons), electrons and...vacuum.
What is the basic unit block of matter that cannot be broken down?
element
What element has formed the largest numbers of atoms?
The most common element in the universe is hydrogen.
Can a element be broken down into compounds?
Elements cannot be broken down into compounds because elements are the simplest form of matter and are made up of only one type of atom. Compounds, on the other hand, are made up of two or more different types of atoms chemically bonded together.
What is water because it is formed from atoms of two element?
It is a Gas,and liquid Water is a COMPOUND because it is formed from atoms of two elements.
