If a neutral atom has a mass of 12 amu and an atomic number of 5, determine the number of protons, neutrons, and electrons in the atom.

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

Which class of molecules functions as chemical signals? hormones water carbohydrates proteins
