Consider a Ca atom with a charge of +2 and a mass number of 44. This type of ion is called a/an
How many protons in the nucleus?
How many neutrons in the nucleus?
How many electrons in the electron cloud?
If this Ca gained 4 new electrons, what would the charge be?

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

the answer is true. hope it .
