The alkali metals in group l of the Periodic Table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.

What happens when sulfur reacts with potassium?
When sulfur reacts with potassium, they form potassium sulfide. This reaction involves the transfer of electrons from potassium to sulfur, resulting in the formation of ionic bonds. The reaction is exothermic, meaning it releases energy in the form of heat.
How many valence electrons are transferred from the nitrogen atom to potassium in the formation of the compond potassium nitride?
Actually. It's 0.
Is pure potassium metallic or covalent?
Potassium is a metallic element; therefore, in pure form it has metallic bonds.
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
How many ions are in potassium ferricyanide?
There are six atoms.There are two ions
what happens to an atoms charge when it loses its electrons?
It becomes positive.
What happens to an object's atoms when the object becomes positively charged.?
They lose electrons.
What happens when sulfur reacts with potassium?
When sulfur reacts with potassium, they form potassium sulfide. This reaction involves the transfer of electrons from potassium to sulfur, resulting in the formation of ionic bonds. The reaction is exothermic, meaning it releases energy in the form of heat.
What a neutral atom gains electrons what happens to the atoms overall charge?
It becomes negatively charged.
What happens to an atoms mass number when it becomes an ion?
it stays the same because you arent losing any protons or electrons
What will happen if ions hits atoms at high speed?
When electrons hit atoms at high speed some of the electrons are knocked away or broken off of the atoms. Once this breakage happens after impact, the atom then becomes a positively charged ion.
What happens to two atoms once they exchange electrons?
Once two atoms exchange electrons, they become ions. One atom becomes positively charged (cation) as it loses electrons, while the other becomes negatively charged (anion) as it gains electrons. This attraction between the oppositely charged ions results in the formation of an ionic bond.
When atoms loses or gains electrons it becomes a?
An ion.
How many atoms in potassium?

What is likely to happen to the electrons when a potassium atom bonds with a chlorine atom?
When a potassium atom bonds with a chlorine atom, the potassium atom donates one electron to the chlorine atom. This transfer of electrons allows potassium to achieve a stable electron configuration, resembling that of a noble gas, while chlorine gains an electron to fill its valence shell. As a result, potassium becomes a positively charged ion (K⁺), and chlorine becomes a negatively charged ion (Cl⁻), leading to the formation of an ionic bond between the two atoms.
What happens to the electrons in a covalent?
The pairs of electrons are shared between atoms.
What describes what happens when an atom becomes an ion with a 2-charge?
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
