yes.
yes it can. yes it can.
Atoms form chemical bond. It is done by exchange of electrons.
Covalent bonds typically form between non-metal atoms, such as hydrogen, carbon, nitrogen, oxygen, and fluorine. These atoms share electron pairs to achieve a full outer electron shell and achieve stability.
Non-metal atoms share electrons to form covalent bonds because they have similar electronegativities, which allows them to achieve a more stable electron configuration. By sharing electrons, both atoms can fill their outer electron shells, often achieving a stable arrangement similar to that of noble gases. This electron sharing leads to the formation of molecules, which are essential for the structure and function of various substances in chemistry and biology.
Sodium atoms will typically lose 1 electron when they react with a nonmetal to form an ionic compound. This electron loss enables sodium to achieve a stable electron configuration similar to that of a noble gas.
When a chlorine atom and a hydrogen atom exchange electrons, the chlorine atom gains an electron to form a chloride ion (Cl-), while the hydrogen atom loses an electron to form a hydrogen ion (H+). This exchange is a type of ionic bond formation where the atoms become charged ions.
Metal atoms usually lose electrons to form positive ions when they combine chemically with atoms of other elements. This allows them to achieve a more stable electron configuration by attaining a full outer shell.
An ionic bond will form between lithium and fluorine atoms because lithium tends to lose an electron and fluorine tends to gain an electron, resulting in the transfer of electrons from lithium to fluorine, creating a strong electrostatic attraction between the oppositely charged ions.
Metal atoms achieve a stable electron shell structure by losing electrons to form positive ions. This electron loss allows them to attain a full outer electron shell like the noble gases. This process of losing electrons is known as metal atoms undergoing oxidation.
Ionic bonds refer to the attraction between metal ions and non-metal ions due to the electrostatic attraction.It is formed by the electron transfer between the metal atoms and the non-metal atoms. It is non-directional and electrically neutral. Electrolysis can be used to separate the ions into their original atoms. p.s. metals always form cations and non-metal always form anions.
No. When atoms share electron pairs they form covalent bonds. Isotopes are atoms having different numbers of neutrons.
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
