Elements are organized on the periodic table based on their properties. Which statement correctly predicts and explains the chemical reactivity of two metals? Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons. Sodium (Na) is more reactive than magnesium (Mg) because sodium atoms must gain more electrons. Calcium (Ca) is less reactive than potassium (K) because potassium atoms must lose more electrons. Beryllium (Be) is less reactive than lithium (Li) because beryllium atoms must gain more electrons.

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

ok whats the question if not i cannot you i need question and need a thing to answer
