They are all metals that share common structures and similar properties that meant them appear identical to one another
Calculate the number of moles for each element. n=m/M Then compare, and which ever one is lowest is the limiting reactant because no more products can form without one or the other.
Answer:
All elements with 84 or more protons are unstable; they eventually undergo decay. Other isotopes with fewer protons in their nucleus are also radioactive.
Answer: option B) proton-electron.
The particles inside a salt crystal are ions. The electrostatic attraction between the positive ions are the negative ions is responsible for the crystal structure. In last stay, the protons are responsible for the positive charge and the electrons for the negative charge. Then you can say that the interaction proton-electron is responsible for the force of attraction between the particles in a salt crystal.
