Bonding Post-assessment

When atoms are bonded, what is it that holds them together?

What determines how close together bonded atoms get at equilibrium?

What is a covalent bond? Why do they form?

What is an ionic bond? Why do they form?

What is a bond that has mixed covalent-ionic character? Why do they form?

What is a metallic bond? Why do they form?

When atoms bond, what happens to their electron density compared to if they were not bonded? How are covalent and ionic bonds different in terms of the electron density change?

What is electronegativity? What causes an atom to have high or low electronegativity?

Why is an atom with a completely filled valence shell stable/unreactive?

When a bond is formed, is energy released or is it required as input? What about when a bond is broken?
