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.
What are the characteristics of group 8A?
Group 8A elements, also known as noble gases, are colorless, odorless, and tasteless gases. They have a full valence shell of electrons, making them stable and unreactive. Their boiling points and melting points increase as you move down the group.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
What is the trend in density as you go down the group of halogens?
The density increase down.
Does halogens reactivity decreese as you mov down the group?
Nope.

Do the halogens become more reactive or less reactive as they go lower down the group?
Halogens become less reactive as you go down the group. This is because atomic size increases down the group, making it more difficult for the larger atoms to gain electrons and react with other substances. Conversely, smaller halogen atoms are more reactive because they can more easily gain electrons and form bonds with other elements.

What is the trend in density as you go down the group of halogens?
The density increase down.
Does halogens reactivity decreese as you mov down the group?
Nope.
What is the density trend in halogens as you go sown the group?
As you move down the group of halogens in the periodic table, the density generally increases. This trend is due to the larger atomic and molecular masses of the heavier halogens, which outweigh the increase in volume. For example, fluorine and chlorine are gases at room temperature, while bromine is a liquid and iodine is a solid, reflecting their increasing densities. Thus, the trend shows that as you descend the group, the halogens become denser.
How does the reactivity of halogens change as you go down group 7?
As you go down group 7 (halogens), reactivity decreases. This is because as you move down the group, the outer electron shells of the halogens are further away from the nucleus, making it harder for them to gain an electron and react with other elements. Additionally, the atomic size increases which leads to weaker intermolecular forces between the atoms.
Where is the halogen gases found on the periodic table?
The Halogens are from Florine and down. They are the group 17 elements.
How does metals or nonmetals change as you go down group 0?
As you go down Group 0 (also known as the noble gases), both metals and nonmetals tend to become less reactive. The noble gases are already very stable and unreactive, and this reactivity decreases even further as you move down the group. Metals in Group 0, called alkali metals, also become more reactive as you go down the group, while nonmetals in Group 0, known as halogens, become less reactive.
Why do halogens become less reactive down the column?
Halogens become less reactive down the column of the periodic table due to the increase in atomic size and the decrease in effective nuclear charge. As you move down the group, the atomic radius increases, leading to a decrease in the attraction between the outer electrons and the nucleus. This decrease in effective nuclear charge results in a weaker hold on the outer electrons, making it more difficult for halogens to gain an electron and exhibit their characteristic reactivity.
Why does reactivity of the halogens decrease down the group?
As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.So, it is said as the reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
