Which occupies a greater about of space free electron pairs or bonding pairs?
bonding pairs, the electrons from each ion reach to the other nuclei because of the inter magnetic force attracting the two atoms. Because the ions must reach to another atoms orbital they require more space than a free electron in a single atom.
What does input force mean?
input force is force exerted on a machine
What are various types of force system?
Coplanar Force ,collinear force &concurrent force
Compares the input force with the output force?
Mechanical Advantage which is the output force divided by the input force.
Is weight mass or force?
Weight is a force - the force with which gravity attracts an object. Therefore, being a force, it is measured in unites of force, usually Newtons.
Why must there be an attractive force to explain existence of stable nuclei?
An attractive force is necessary to explain the existence of stable nuclei because it overcomes the repulsive electrostatic forces between positively charged protons within the nucleus. This attractive force, known as the strong nuclear force, acts over very short distances and helps bind the protons and neutrons together to form stable nuclei. Without this force, the nucleus would not be able to stay together due to the repulsion between protons.
When are heavy nuclei most stable?
Heavy nuclei are most stable when their neutron-to-proton ratio approaches 1. Nuclei with too many or too few neutrons compared to protons will have higher instability. This balance contributes to stability by preventing the repulsion between protons from overpowering the attractive nuclear force.
Why is a larger nucleus not as stable as a smaller nucleus?
A larger nucleus has a higher number of protons, which results in stronger repulsive forces between the positively charged protons. This can lead to instability as the repulsive forces can overcome the attractive nuclear force, causing the nucleus to be less stable and more likely to undergo radioactive decay.
What provides the stability that occurs in larger atomic nuclei?
The strong nuclear force provides the stability in larger atomic nuclei by overcoming the repulsive electromagnetic forces between protons. This force binds protons and neutrons together in the nucleus, making the atom stable.
What are the relative strength strengths of attractive and repulsive forces in a stable nucleus?
In a stable nucleus, the attractive nuclear forces (such as the strong nuclear force) are stronger than the repulsive forces (such as the electromagnetic force) between protons. This balance of forces keeps the nucleus stable and prevents it from breaking apart.
What is a strong attractive force in an atomic nucleus?
The strong nuclear force is a powerful attractive force that binds protons and neutrons together in the atomic nucleus. It overcomes the electrostatic repulsion between positively charged protons to keep the nucleus stable.
What are the attractive and repulsive forces involved in a covalent bond and how do their total strengths compare?
In a covalent bond, the attractive force is the sharing of electrons between atoms, which binds them together. The repulsive force arises from the negatively charged electrons and positively charged nuclei pushing against each other. The total strength of the attractive force between the shared electrons and nuclei is typically stronger than the repulsive force, stabilizing the bond.
What do a heavy nuclei need to remain stable?
Heavy nuclei need to have a balanced ratio of protons to neutrons to remain stable. They also need to have the strong nuclear force between nucleons overcome the electrostatic repulsion between protons. Additionally, the nuclei need to have a sufficient binding energy to hold the nucleus together.
Give the characteristic of nuclear force?
The nuclear force is a strong attractive force that acts between nucleons (protons and neutrons) in the atomic nucleus. It is a short-range force that overcomes the electrostatic repulsion between positively charged protons in the nucleus, holding the nucleus together. The nuclear force is responsible for binding protons and neutrons together to form stable atomic nuclei.
A chemical bond is an attractive what that holds atoms together?
A chemical bond is an attractive force that holds atoms together by sharing, gaining, or losing electrons.
Holding electrons in orbit around atomic nuclei is an electric force of what between what and what?
Holding electrons in orbit around atomic nuclei is an electric force of attraction between the positively charged protons in the nucleus and the negatively charged electrons. This force is known as the electromagnetic force and it keeps the electrons bound to the nucleus, creating stable atoms.
What is an attractive force that holds atoms together to form a compound?
The attractive force that holds atoms together to form a compound is called a chemical bond. This bond is a result of the sharing or transfer of electrons between atoms, allowing them to achieve a more stable electron configuration.
