Describe how the reactivity of Group 7 Halogens changes as you move down the column Explain why this happens?
The reactivity of Group 7 halogens decreases as you move down the column from fluorine to iodine. This is because atomic size increases down the group, leading to weaker intermolecular forces of attraction between atoms. As a result, it becomes harder for the halogens to gain an extra electron and they become less reactive.

One chemical property of substance is its density or not?
Density is a physical property of a substance, not a chemical property.Density is a measure of how much mass is contained in a given volume of a substance. Chemical properties describe how a substance interacts with other substances, such as its reactivity or ability to undergo chemical changes.
What is vascular reactivity?
Vascular reactivity refers to how blood vessels respond to various stimuli, such as hormones, drugs, or physical factors like temperature or pressure. It can impact blood flow, blood pressure regulation, and overall cardiovascular health. Changes in vascular reactivity are often seen in conditions like hypertension or atherosclerosis.
What are the two types of chemical properties of reactivity are the ability to and the ability to?
The two types of chemical properties related to reactivity are the ability to undergo chemical reactions and the ability to bond with other substances. Reactivity is determined by how easily a substance can react with other substances or undergo chemical changes, often influenced by its electron configuration and bonding tendencies.

What substance with a high will undergo chemical changes easily?
A substance with a high reactivity will undergo chemical changes easily. Substances like alkali metals (e.g., sodium, potassium) and halogens (e.g., chlorine, fluorine) are highly reactive due to their tendency to gain or lose electrons easily, leading to rapid chemical reactions.

The purpose of adding hexane to the aqueous solutions of halogens?
Hexane is a nonpolar solvent that helps extract nonpolar compounds, such as halogens, from an aqueous solution. By adding hexane, the halogens will preferentially dissolve in the nonpolar layer, allowing for easier separation and purification of the halogens from the aqueous solution.
How do you use Reactivity in a sentence?
A atoms reactivity is the certainty to transfer or share electrons forming a chemical bond.
What is the ability of a substance to undergo or resist chemical changes?

What do yo mean by neighbouring group effect explain?
The neighboring group effect refers to the influence that a functional group or substituent has on the reactivity of a nearby functional group in a molecule. This can include both intramolecular interactions that affect the outcome of chemical reactions, as well as changes in the stability or reactivity of a functional group due to the presence of neighboring groups.
What are the examples of reactivity?
Examples of reactivity include chemical reactions, the tendency of some metals to corrode when exposed to air or water, the flammability of certain substances, and the responsiveness of a system to changes in its environment.
What is the ability to cause changes in matter?
Kinetic energy
