Metal atoms will most likely form ions by the 1 loss of protons. 2 loss of electrons. 3 gain of electrons. 4 gain of protons.

2 loss of electrons.

Explanation:

An atom of any element either metal or nonmetal form ions by losing or gaining electron. This is because protons are embedded in the nucleus with neutrons and electrons are found in different orbits surround the nucleus.

Metals have 1 or 2 or 3 electrons in their outermost shell which is called valence shell and electrons in these shell is called valence electron.So they lose electrons to form ions.Metals lose electrons and positively charged ions called cations.

Whereas nonmetals have 5 or 6 or 7 electrons in their outermost shell so they gain electrons to form ions.

For example Aluminium is a metal having electronic configuration (2,8,3). That means aluminium have 3 electrons in its valance shell so it loses its electrons to become a positively charged ion.

Another one is Sodium a metal having electronic configuration (2,8,1). That means aluminium have 1 electrons in its valance shell so it loses its electrons to become a positively charged ion.

3 hours because it is a decent distance.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
