Hi:) I really need help with this, I’m so confused! :/
Metals tend to lose electrons to achieve a stable noble gas electronic configuration.
Do metals lose electrons to other metals
OR
Do metals lose electrons to non metals

Non-metals tend to gain electrons to achieve a stable noble gas electronic configuration
Do non metals gain electrons from other non- metals
OR
Do non-metals gain electrons from metals?

Hi, I believe this should belong in the chemistry section. But nevertheless, here is the solution,

To achieve a noble gas electronic configuration, the overall charge has to be 0 as noble suggest stable.

For such configuration to happen, in your syllabus, when the question mentions LOSING / GAINING electrons, it is referring to ionic bonding.

For ionic bonding to occur, metal atom must be bonded to a non-metal atom.

A metallic ion like sodium ion is always +1 charge

A non-metallic ion like chlorine ion is always -1 charge.

So for a stable Sodium Chloride/NaCl to achieve a noble(stable) state, an electron will be lost chlorine ion where this electron will be gained by sodium ion.

When chlorine ion (-1 charge) loses an electron, it becomes 0 charge, which is stable.

When sodium ion(+1 charge) gains an electron, it becomes 0 charge which is stable.

And hence both are stable and formed the stable noble compound called NaCl.

You yeah with the side of the yeah with a little bit of yeah.

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
