Differences between alkil metals and halogens?
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
What is the most characteristic property of halogens?
A: 1. The halogens show a number of trends when moving down the group—for instance, decreasingelectronegativity and reactivity, and increasingmelting and boiling point. 2. Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells resulting in trends in chemical behavior.
What properties do halogens have?
Halogens have many properties but the most important is the high reactivity and high electonegativity.let example of flourine it is so much high reactive that even if it react in dark still it will creat an explosion.
What halogen is most likely to react?
The reactivity of halogens decreases down the group, which means Fluorine is the most reactive halogens as it is the most electronegative elements among the halogens, and also the Periodic Table.
Why are the halogens not found naturally in the earth's crust as the pure elements?
The halogens are not found naturally in the earth's crust as pure elements because of their extreme reactivity. Because the halogens are close to having completely filled electron shells, they will often react with other substances in order to gain an electron. As an especially noteworthy case, fluorine is the most reactive of the halogens (and elements in general), and will even react with glass. Therefore, the halogens are found naturally as compounds, not pure elements.
What can you tell about an atom that has high electronegativity?
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
Do the halogens have a high or low melting points?
They have low melting points and high reactivity.
What is the reactivity for the halogens?
The reactivity of halogens decreases with increasing atomic number.
What can you tell about an atom that has a high electro negativity?
It is more likely to attract electrons. :)
What are examples of high reactivity?
Very reactive elements are alkali metals and halogens.
What is the family of nonmetal elements with high reactivity?
The halogens are a family of nonmetal elements with high reactivity. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens readily form compounds with metals to achieve a stable octet configuration.
An element is classified as a halogen What properties would the halogen be expected to have?
Halogens are expected to have properties such as high reactivity, tendency to form salts with metals, and exhibit diatomic molecules in their elemental form. They are typically nonmetals, have high electronegativity, and appear in Group 17 of the periodic table. Some common halogens include fluorine, chlorine, bromine, and iodine.
Do halogens have high or low ionization energies?
no it does not
What property of halogens is harmful?
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to highelectronegativity and high effective nuclear charge.
Do you think the reactivity of the halogens is influenced by the shielding effect?
Yes, the reactivity of halogens is influenced by the shielding effect, which is the ability of inner electron shells to shield the outer electrons from the positive charge of the nucleus. This affects the ease with which outer electrons can be gained or lost, impacting the reactivity of the halogens.
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.
How does reactivity change as you move vertically among the halogens?
As you move from Astatine to Fluorine the reactivity increases
