Why do atoms gain, lose, or share electrons?

Biology

Mnenie [13.5K]3 years ago

Atoms gain, lose, or share electrons to gain a full outer, valence shell. Since most atoms have an outer shell that isn't completely full, they will bond with other atoms or ions to gain a full valence shell. 

(Side note: This is why noble gases do not bond; they already have a complete valence shell.)

Hope this helps!

Heart has a pacemaker that will continually send a signal. The primary site of the pacemaker is at the sinoatrial node, on the top right atrium. This node will send a signal to atria (which will cause it to contract) and to the atrioventricular node.
Atrioventricular node located between atrium and ventricle. It will send the signal to the ventricle(by the bundle of his) and cause it to contract.
