When atoms share electron - Study guides, Class notes & Summaries

Which subatomic particle is displaced when two or more atoms combine make a molecule? Correct Answer-Electrons What type of bond is formed when atoms share electrons? Correct Answer-Covalent What determines the number of covalent bonds an atom can create? Correct Answer-the excess or shortage of electrons in its outermost electron shell. Oxygen with 6 electrons in the outer electron shell (that needs 8 to be complete), can make how many covalent bonds? Correct Answer-2 Which of the f...

chemical bond CORRECT ANSWER the force that holds two atoms together Atoms gain stability when CORRECT ANSWER they share electrons and form covalent bonds. The stability of an atom, ion or compound is related to its energy: CORRECT ANSWER lower energy states are more stable Metals and nonmetals gain stability by CORRECT ANSWER transferring electrons (gaining or losing) to form ions that have stable noble-gas electron configurations. Another way atoms can gain stability is CORRECT ANS...

Covalent bonds: Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds: Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond: Share electrons with nonmetal to form a covalent bond Ionic bond: transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron acceptor (cation and anion) Covalent: water, H2O 2 H atoms + 1 O ato...

Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energ...
