I am an electrician and have started my own business can you pls help me come up with a slogan?

i’m trying to figure out some questions about metals, but the questions are phrases very strangely and i’m not sure which name goes with what. can anyone tell me:
what are substances with moderate electrical conductivity known as? this includes what group of elements?
what is the process by which their conducting abilities are increased by?
so i’m guessing the name “metals” should fit into one of these?

Just a random inquiry that popped into my head earlier today.

How does the strength of electrical and gravitational forces between two nitrogen-14 nuclei change if one nuclei becomes an atom by the addition of 7 electrons? Does this change the electrical or gravitational forces between the two, how does it affect the strengths of these forces?

All sites I’ve visited seem to show exactly the same result: a long-chain fatty acid with a carboxylate salt at the end! But I know this can’t be true, since you can’t run diesel engines on soap! Can anyone clarify the difference?

I have lots of AC adaptors, mobile phone chargers, network cables, ethernet/USB cables etc that I don’t need but I don’t want to just chuck them into normal waste. It’s all wires and cables…
Can anyone advise me on how to recycle them or get rid of them responsibly?

It was featured on the front pages of entertainment and gossip magazines and such…opinions please, thanks.

I would be grateful if any one can help me work out this problem. Thank you very much.

And doesn’t smell horrible?
