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+
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.
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.
Chemists typically use substances that have distinct physical or chemical properties to separate mixtures into individual components. These characteristics can include differences in solubility, boiling points, and polarity. Common substances employed in separation techniques include solvents for liquid-liquid extractions, stationary phases for chromatography, and reagents that selectively react with certain components in a mixture. The choice of separation method and materials depends on the nature of the mixture and the desired purity of the separated substances.
Chemical: Toxicity is about a harmful material interacting chemically with other substances in the body.
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.
Substances together, but can be separated.

Yes.
They both have ONE PHASE ONLY.

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 those substances would be physical traits, also known as physical properties.
