-1
When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
halogens
The halogens typically have an ionic charge of -1 when they form ions by gaining an electron to complete their octet electron configuration.
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.
-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
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.
Neutron is electrically neutral... But it posses a spin... And when it moves it has a finite kinetic energy...
Hydrogen posses properties of alkali metals while it also posses properties of halogens .That is why it cannot be placed in any of the either groups ,so it has been given a distinct place in modern periodic table. NOTE Hydrogen does not belong to group 1
Most common is -1. But halogens (except fluorine) are known to exhibit oxidation numbers upto +7 in their compounds.
zwitter ion eg. proteins
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.
Minecraft does not charge you to run a server for the game. You will, however, have to posses a computer to be the server. Otherwise you will have to rent a server to run for you, which costs money.
