Sulfur forms covalent bonds with chlorine and carbon, but forms ionic bonds with calcium and lithium. What is the BEST description for this difference in how oxygen behaves?
A. Sulfur bonds randomly with elements in unpredictable ways
B. Sulfur bonds with elements that have a smaller atomic mass
C. Electronegativity differences between bonding elements allow electrons to be either shared or donated
D. The difference in atomic radii between the groups accounts for the difference in behavior

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
