- The characteristics that enable us to distinguish one substance from another are called properties. A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

May 10, 2019 · Basically, physical properties are those which you can observe and measure without changing the chemical identity of your sample. Physical properties are used to describe matter and make observations about it. Examples of physical properties include color, shape, position, volume and boiling point.

Mar 17, 2023 · Most of the atom is empty space. The rest consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The nucleus is small and dense compared with the electrons, which are the lightest charged particles in nature.
- What is an atom?An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically char...
- Are all atoms the same size?All atoms are roughly the same size, whether they have 3 or 90 electrons. Approximately 50 million atoms of solid matter lined up in a row would me...
- What does the mass of an atom consist of?The mass of an atom consists of the mass of the nucleus plus that of the electrons. That means the atomic mass unit is not exactly the same as the...
- How is the atomic number of an atom defined?The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z), which is defined as the number of units...
