Covalent bonding. the bond result whenever unequal sharing of electrons is called non polar covalent bond. The electrons involved are in the outer shells of the atoms. That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus. A covalent bond forms when two non-metal atoms. share a pair of electrons. this is just … When free electrons recombine with hydrogen nuclei, the electrons cascade down the energy levels, emitting photons as they go. The atoms are not really sharing electrons as much as they are fighting over them this creates a force that makes the atoms stick together 2 The electrons of one atom separate to form electron particles. That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus. What happens when the nuclei of two atoms combine? Atoms combine with other atoms in order to become stable, which for most atoms means having 8 valence electrons. A Chemical Bond is a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.Energy is the energy required to break a chemical bond and form neutral isolated atoms.Likewise, a Shared Pair is a pair of electrons that is shared between two atoms. The electrons of two atoms combine to form a cluster of electrons. The nucleus of one atom splits to form two smaller nuclei. Asked in Science When wood burns what happens to its atoms ?
