Which choices are correct based on the images providedwhat causes atoms to form covalent bonds? each atom and the shared electronsthe nuclei of the two atomsthe valence electrons of the two atomsenergy levelsprotons and neutronsvalence electrons

each atom and the shared electrons,

valence electrons

Explanation: A covalent compound is defined as the compound which is formed from the sharing of electrons between the element that are combining together.

These compounds are most likely to be formed when two non-metals combine together. For Examples:

Flourine is an element with tomic number 9 and has 7 valence electrons

Thus for formation of  a molecule, they share their valence electrons and attain stable configuration.

i'm assuming that the correct answer is indeed the first one/ "a"..

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
