Αand β rays consist of particles, whereas γ rays are high-energy radiation and contain no particles and thus they have no mass. given that the penetrating power decreases with mass, rank the rays according to their penetrating power. rank the components from strongest penetrating power to weakest penetrating power. to rank items as equivalent, overlap them.

γ > β > α

Explanation:

The penetrating power is inversely related to the mass. The higher the mass, the lower the penetrating power.

α rays are Helium nucleus (He²⁺), that is, they are formed by 2 protons and 2 neutrons. The mass of an α particle is 4.001 amu.

β rays are nuclear electrons, which result from the decay of a neutron. The mass of a β particle is 1/1840 amu.

γ rays contain no particles and have no mass.

The order of penetrating power is γ > β > α.

gravity causes stares to cluster i think so

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
