How much 0.25 M HCl solution can be made by diluting 500 mL of 10 M
HCI?

neutrons are in the middle of the atom and the electrons, which are much smaller.

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.

i don't know people like to fight everywhere rip.
