What accounts for the observed differences in the properties of ionic and molecular compounds?
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
Explain why most metals bend when struck but most ionic solids shatter?
Most metals have a metallic bond that allows the atoms to slide past each other when a force is applied, making them malleable. In contrast, ionic solids have strong ionic bonds holding the atoms in a fixed position, so when a force is applied, the structure lacks flexibility and breaks, causing the material to shatter.
How brittle are ionic compounds?
Ionic compounds are generally brittle because the ionic bonds within them are strong and rigid. When a force is applied, the layers of ions in the crystal lattice can shift and become misaligned, causing the structure to break instead of bending.
Why metals are flexible?
Metals are flexible due to the arrangement of their atoms in a crystalline structure. The atoms in metals are closely packed together in layers, allowing them to slide past each other when a force is applied. This ability to deform without breaking is what gives metals their flexibility. Additionally, the presence of metallic bonds, where electrons are free to move throughout the material, also contributes to the malleability and ductility of metals.
Which is the reason that ionic compounds are brittle?
Ionic compounds are brittle because their strong ionic bonds hold the ions in a rigid lattice structure. When a force is applied to the crystal structure, the ions of the opposite charge align and repel each other, causing the crystal to shatter.
What is the difference between shock load and gradually applied loads and suddenly applied Load?
The only difference between a shock load and a gradually applied load is something called an impulse; defined as the integral of a force with respect to time. When a force is applied to a rigid body it changes the momentum of that body. A small force applied for a long time can produce the same momentum change as a large force applied briefly, because it is the product of the force and the time for which it is applied that is important.
What is the difference between impulse and force?
Impulse is the force applied on an object multiplied by the time during which the force is applied. To illustrate the difference, a large force applied during a short time may have a lower impulse than a smaller force applied for longer.
What is the net force when encounters 15 N air resistance?
The net force would be the difference between the applied force and the air resistance. If the applied force is greater than the air resistance, then the net force would be in the direction of the applied force. If the air resistance is greater than the applied force, then the net force would be in the opposite direction.
If the same force is applied to two different objects what will determine the difference in their motion?
the mass and the amount of force
What is the difference between plane of application and direction of force?
The plane of application refers to the surface on which a force is acting, such as horizontal or vertical. The direction of force describes the path along which the force is applied, such as pushing or pulling. In essence, the plane of application identifies where the force is being applied, while the direction of force indicates how the force is being applied.
Do non-metals elements which are solid at room temperature break when they are hit?
Some do break, depending on the strength of the force applied.
What is the difference between the direction of force and the plane of application?
The direction of force refers to the line along which a force is applied, indicating its push or pull. The plane of application is the surface on which the force is exerted. In essence, the direction of force shows the path of the force, while the plane of application denotes where the force is applied.
What is Difference between input force and output force?
The input force is the force applied to a machine to make it work, while the output force is the force generated by the machine in response to the input force. The output force is what produces the desired work or movement from the machine based on the input force applied.
Why are metals malleable and ductile?
Metals are malleable and ductile because of their atomic structure. The atoms in metals are arranged in a regular pattern that allows them to slide past each other easily when a force is applied. This allows metals to be shaped and stretched without breaking.
What is the difference between axial load and radial load?
Axial load (or thrust load) is a force applied parallel to the longitudinal axis, whereas, a radial load is a force applied transverse to this longitudinal axis.
You push the ball with force of 22.8N which induces a -2.3N frictional force. what is the net force while you push the ball?
The net force is the difference between the applied force and the frictional force: 22.8N - 2.3N = 20.5N.
If you are pushing on a box with a force of 20 N and there is a force of 7 N on t he box due to sliding friction what is the net force on the box?
The net force on the box is the difference between the applied force and the force of friction. In this case, the net force on the box is 13 N (20 N - 7 N) in the direction of the applied force.
