Answer:
Ca is larger than the Ca2+ because Ca2+ has a greater positive charge and electrons repel the nucleus.
Number of moles ( n ) = ?
Volume ( V ) = 0.25 L
Molarity of solution ( M ) = 2.00 M
n = M x V
n = 2.00 x 0.25
n = 0.5 moles of Ba(NO₃)₂
hope this helps!
Answer: The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks.
Explanation:
Hydrogen and helium because they only have one electron shell and it only holds up to two electrons in it.
