Answer:
Electronegativity in group 1 decreases as we go from Lithium to Francium.
Explanation:
Electronegativity is defined as the tendency of an element to attract an electron pair towards itself.
In a group generally this tendency decreases from top to bottom as the size of the atom increases and hence the positive nucleus get far from the outer orbital.
In the same way group 1 elements i.e. from Lithium to Francium electronegativity decreases.
equilibrium
Heat transfers from a body with high temperature to a body with low temperature until both bodies are in the same temperature.
The correct answer is ELECTRON. The part of an atom that is actively exchanged or shared in a chemical bond in the electron. Electron are negatively charged atoms.
Answer:
False
Explanation:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
- A phase change is a change in the physical state of a body.
- In this change, it is from solid to liquid.
- Now new substances are formed.
- When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.
