The atomic mass of hydrogen is 1.01 g/mol. What percentage of H atoms have an atomic mass of 1.01 amu? a. 0
b.100
c. 33
d. 66

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

idk i’m struggling too

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
