How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
What charge do alkali metals form when they react with a halogen?
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
What is the charge for elements in group 17?
Elements in group 17 of the periodic table are called halogens. They have a charge of -1 when they form ions by gaining one electron to achieve a full outer shell of electrons.
Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
What period 3 diatomic elements will form ions with a negative 2 charge?
Only chlorine has a diatomic molecule biut any ion is 2-..
What is the ionic charge of the halogens?
The halogens typically have an ionic charge of -1 when they form ions by gaining an electron to complete their octet electron configuration.
What group of elements tends to form negative ions that have a -1 charge?
Group that tend to form -1 ions include group VIIA
Why are halogens the most stable ionic charge?
Halogens are the most stable in their group because they have a full outer shell of electrons when they gain one electron to form a 1- charge. This full outer shell allows halogens to achieve the electron configuration of a noble gas, making them more stable.
What charge do halogens have when they become an ion?
-1 charge.because they have seven valence electrons, halogens tend to share one electron or gain one electron to attain a stable, noble -gas electron configuration. they tend to form ions with a 1- charge
What group of elemets will most likely form an ion with a -1 charge?
The halogens, listed in column 17 of a wide form periodic table.
What charge do Halogens posses?
-1
Do halogens form diatomic molecules?
Yes, halogens form diatomic molecules.
Why are halogens known as salts?
Halogens are not salts but they are chemical elements; halogens can form salts reacting with metals.
What family on the periodic table has a -1 charge?
halogens
What typically form ions with a 1- charge?
The halogen (group 17/VIIA) atoms form ions with a 1- charge when undergoing ionic bonding. An atom gains one electron from a metallic element, resulting in the metal developing an ion with a 1+ charge. The electrostatic attraction between the oppositely charged ions forms the ionic bond.
What are two prperties of the halogens?
They have low melting and boiling points which increases down the group. They form diatomic molecules They form simple ions with -1 charge They react with hydrogen to form acidic compound
What group in the periodic table contains elements whose atoms form ion with a 1- charge?
Group 17, also known as the halogens, contains elements whose atoms form ions with a 1- charge. This is because halogens have 7 valence electrons and gain 1 electron to achieve a stable 8-electron configuration, forming an anion with a 1- charge. Examples of halogens include fluorine, chlorine, bromine, and iodine.
