1) False

An anion is a negative ion. When an atom loses valence electrons (i.e. loses negative charge) it becomes a positive ion (called cation, not anion).

2)  True

Non metals are at the right side of the periodic table. Those elements tipically have more than four valence electrons (except C which has 4 valence electrons). Then, by gaining some electrons (the number depends on the number of valence electrons that the non metal has),  they can complete the 8 valence electrons configuration of the nobles gases.

When does hydrogen first begin to fuse into helium in the star formation process?
valentina_108 [34]

Step one of the Hydrogen fusion process helium  a nucleus of Deuterium is formed from two protons with the emission of an antielectron and a neutrino.

The fundamental Hydrogen fusion cycle includes 4 Hydrogen nuclei  and two electrons and yields a Helium nucleus, two neutrinos and six photons. The principle series phase is the stage in development where the center temperature reaches the point for the fusion to begin. in this manner, the protons of hydrogen are converted into atoms of helium.

If the star is big sufficient to fuse hydrogen atoms into helium, it's going to enter the phase that our solar is in, referred to as the primary sequence section. a celebrity will enjoy most of its existence in the major series section. At this point nuclear fusion is turning hydrogen into helium.

A star isn't always absolutely a star until it is able to fuse hydrogen into helium. before that, they are called Protostars. A protostar is fashioned as gravity begins to tug the gases together right into a ball. This process is referred to as accretion.
