When an atom loses one electron it forms an ion. The atom becomes charged. It has more positive charges in its nucleus than negative electrons surrounding it, so the charge is positive, it has made a positive ion.
The same happens when an atom gains an electron apart from the charge now becomes negative.
Each atom always wants to become stable.
The electron arrangement is 2,8,8,8... and so on.
So for example sodiums atomic proton number is 11 and is set out like 2,8,1.
It needs to loose 1 electron to become stable.
Its ion is represented as Na+

what are characteristics of chemical equation?
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
What is a substance that cannot be broken down into simpler substance with all the characteristics of the substance?
An element is a substance that cannot be broken down into simpler substances with all the characteristics of that element. Elements are composed of only one type of atom and they cannot be chemically decomposed into simpler substances.
Is toxicity chemical or physical property?
Chemical: Toxicity is about a harmful material interacting chemically with other substances in the body.
What is heterogeneous physical?
Heterogeneous physical refers to a system where the components or substances within it are not uniform or of the same kind. This means that there are different types of materials or substances present within the system, displaying varying physical properties or characteristics.
When two substances react to form a new material with different properties what occures?
This is a chemical reaction where the two substances undergo a chemical change to form one or more new substances with different properties from the original substances. The atoms are rearranged to form new chemical bonds, leading to the creation of the new material with distinct characteristics.
What are characteristics of mixture?
Substances together, but can be separated.
What are mixtures characteristics?

What and what of matter are characteristics that can be observed without changing the composition of substances?
Physical properties of matter, such as color, texture, density, and melting point, can be observed without changing the composition of substances. These characteristics help identify and classify different types of matter based on their observable features.
The traits of substances that can be observed or measured without changing their chemical identity?
The traits of those substances would be physical traits, also known as physical properties.
When 2 substances combine but do not lose their original characteristics do they form a mixture?
Yes, it is true, a mixture is formed.
