2 days ago · Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2] : 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
3 days ago · In physics, angular momentum (sometimes called moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity – the total angular momentum of a closed system remains constant.

2 days ago · atom, the basic building block of all matter and chemistry. Atoms can combine with other atoms to form molecules but cannot be divided into smaller parts by ordinary chemical processes. Explore an atom's interior to discover the layout of its nucleus, protons, and electrons. See all videos for this article.
- 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...
1 day ago · In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.
