the.com/ionic bond
One atom hoards the electron, the other sulks into a permanent charge, and somehow that's love.
means A chemical bond formed when one atom donates an electron to another, creating oppositely charged ions that stick together through electrostatic attraction.
from From 'ion,' coined by scientists in the 1830s from the Greek 'ienai,' meaning 'to go' — ions were named for the way they migrate toward electrodes during electrolysis, one heading to the anode, the other to the cathode. 'Bond' is the plain old English word for a binding tie, used here as it is in rope or marriage. The term 'ionic bond' itself came into chemical use in the early 20th century, once scientists understood that atoms could trade electrons and end up permanently charged, then locked together by that charge.
- the mechanism
- electron fully transferred, not shared like in covalent bonds
- classic example
- sodium gives, chlorine takes, you get table salt
- the result
- forms rigid crystal lattices, not single molecules
- the giveaway
- high melting points, dissolves readily in water
