Metals lose electrons and form cations to get a full octet.
Metals donate electrons by losing electrons and forming positive ions.
Metals have "free" electrons, the free electrons in metals help to transfer heat together with the vibrating atoms.
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
Metals and non metals attain stable configurations by ionic bonding.
metals lose electrons when they react with a non-metal

They become positively charged ions.
Atoms of non-metals usually gain or share electrons when they react with other atoms.

Since this is a metal it is going to lose electrons. Metals lose the electrons while nonmetals gain electrons.
Metals lose electrons to become positively charged but stable. The electrons they lose are accepted by the non-metal to become negatively charged but stable.
Metals generally become cations and thus lose electrons and their atomic radius shrinks. This is because the metals will lose a shell of electrons and the nucleus' pull on the electrons will become more concentrated, pulling them closer.
