What is the mass of an atom that has 3 protons, 4 neutrons, and 3 electrons?
the correct answer is a liter.
the si or the international system of units illustrates seven measuring units as a fundamental set from which all the other si units can be obtained. the si base units and their physical quantities are the kilogram for mass, the meter for measurement of length, the ampere for electric current, the second for time, the candela for luminous intensity, the kelvin for temperature, and the mole for the amount of substance.
ionic bonds \
the result is a bond where the electron pair is displaced toward the more electronegative atom.
