The halogens have 7 electrons in their outer shells. This is not a very stable setup, but an outer shell with 8 electrons is stable. Because of this, a halogen will tend to gain 1 extra electron to fill this space. An electron carries a 1- charge.
What else can I help you with?
How do halogens react with air?
Halogens react with air to form metal halides. For example, chlorine will react with iron to form iron(III) chloride. Halogens are highly reactive and will readily form compounds with many elements in the air.
Halogens combine with most metals to form salts?
That is correct. Halogens like chlorine, bromine, and iodine readily react with metals to form ionic compounds called salts. For example, sodium chloride (table salt) is formed when sodium metal reacts with chlorine gas.
What do active metals and halogens have in common?
Active metals and halogens both have a strong tendency to form ions by gaining or losing electrons in reactions. Active metals readily lose electrons to form positive ions, while halogens readily gain electrons to form negative ions. Both groups of elements exhibit high reactivity due to their desire to achieve a stable electron configuration.
Which group of elements is know as the halogens?
The halogens are a group of elements in the periodic table consisting of fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals that readily form salts with metals.
Halogens are only found in nature as what?
Halogens are found in nature primarily as salts, such as sodium chloride (table salt) or potassium iodide. They are highly reactive nonmetals that readily form ionic bonds with metals to create mineral salts.
What are highly reactive and readily form salts with metals?
Halogens, such as fluorine, chlorine, and bromine, are highly reactive non-metal elements that readily form salts with metals. They easily gain an electron to achieve a full outer electron shell and form ionic compounds with metals.
How do halogens react with air?
Halogens react with air to form metal halides. For example, chlorine will react with iron to form iron(III) chloride. Halogens are highly reactive and will readily form compounds with many elements in the air.
What is the family of elements that react readily with metals?
The family of elements that react readily with metals is the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form compounds with metals by gaining an electron to achieve a stable electron configuration.
Do halogens rarely combine with other elements?
No. Halogens combine readily with sodium
What happens when Sodium and Hydrogen form plus 1ions?
they lose their outer electron to some other atom.
How do the chemical properties of the alkali metals and halogens that react to form them?
Alkali metals, like sodium and potassium, have one valence electron and readily lose it to form a +1 cation. Halogens, like chlorine and fluorine, have seven valence electrons and readily gain one electron to form a -1 anion. When alkali metals react with halogens, the alkali metal donates its electron to the halogen, forming an ionic compound.
Halogens combine with most metals to form salts?
That is correct. Halogens like chlorine, bromine, and iodine readily react with metals to form ionic compounds called salts. For example, sodium chloride (table salt) is formed when sodium metal reacts with chlorine gas.
Which group of p block elements react to form halides?
Group 17 elements, also known as the halogens, are the p block elements that react to form halides. They readily react with other elements to form salts called halides, such as sodium chloride (NaCl) and potassium iodide (KI).
What do active metals and halogens have in common?
Active metals and halogens both have a strong tendency to form ions by gaining or losing electrons in reactions. Active metals readily lose electrons to form positive ions, while halogens readily gain electrons to form negative ions. Both groups of elements exhibit high reactivity due to their desire to achieve a stable electron configuration.
Which group of elements is know as the halogens?
The halogens are a group of elements in the periodic table consisting of fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals that readily form salts with metals.
Which group of elements most readily combines with group 17 elements?
Group 1 metals, such as sodium and potassium, readily combine with group 17 elements (halogens) to form salts. These metals have one electron in their outermost shell, which they can easily lose to achieve a stable electron configuration, while halogens are one electron short of a stable configuration and readily accept an electron to form a stable ion.
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.
