What happens to the atom or molecules of a substance if it melts?
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
What happens to a bromine atom when it enters a chemical reaction with an active metal?
A bromide is formed.
What describes the substance that is made up of only one kind of atom and cannot be broken down by chemical reaction?
This is an element.
What happends to an atom in a chemical reaction?
The substance(s) change from one thing into something completely different, and the new substance can not seperate back into the initial substances
A atom loses an electron to another atom is an example of physical or chemical change?
This is an example of a chemical change. When an atom loses an electron to another atom, it undergoes a chemical reaction, resulting in the formation of new chemical compounds with different properties.
Is fire an atom?
no it is a chemical reaction!
What describes a substance that is made up of only one kind of atom and cannot be broken down by chemical reaction?
An element is a substance made up of only one kind of atom and cannot be broken down by chemical reactions.
Is displaces hydrogen from an atom a physical or chemical property?
Displacing hydrogen from an atom is a chemical property, as it involves a chemical reaction that results in a change in the substance's composition and properties. Physical properties, on the other hand, are those that can be observed or measured without changing the substance's chemical composition.
What is the smallest part of a substance made from more than one atom that stilll has the same proerties of the substance is a?
The smallest part of a substance made from more than one atom that still retains the properties of the substance is a molecule. A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
What happens to the atom of the starting substances during a chemical reaction?
The atoms rearrange and the new bonds form to make the new substances.
When some atoms go away why don't they come back?
They react with another atom, making a new substance entirely. This is called a chemical reaction.
