Chemistry 130 Arizona College of Nursing Midterm Questions with Verified Solutions What is the atomic number of an element, and why is it important? The atomic number is the number of protons in an atom’s nucleus and determines the element's identity and position on the periodic table. How does an ionic bond form between atoms? An ionic bond forms when one atom donates an electron to another atom, creating oppositely charged ions that attract each other. What is the diffe...

MCAT Study Setcovalent bond formed via the sharing of electrons between two elements of similar EN bond order refers to whether a covalent bond is a single, double, or triple bond. As bond order increases, bond strength increases, bond energy increases, bond length decreases ionic bonds formed via the transfer of one or more electrons from an element with a relatively low IE to an element with a relatively high electron affinity - cation: postiive - anion: negative elect...

In the case of H20, the oxygen atom covalently bonds unequally with 2 hydrogen atoms. This is why H20 is considered a _______ molecule. - polar Electrons are not evenly distributed; at any instant, they may accumulate by chance in one part of a molecule or another, causing every-changing regions of positive and negative charge that enable all atoms and molecules to stick to one another, known as - Van der Waals interactions. Which statement is true of all atoms that are anions? - The atom h...
