Using the periodic table of the elements, the properties of elements can often be used to deduce the properties of neighboring elements. In which set can the reactivity of the first three elements be used to most accurately predict the reactivity of the fourth element? A. silver (Ag), sodium (Na), strontium (Sr) → sulfur (S)
B. fluorine (F), oxygen (O), nitrogen (N) → carbon (C)
C. antimony (Sb), tellurium (Te), iodine (I) → xenon (Xe)
D. oxygen (O), sulfur (S), tellurium (Te) → selenium (Se)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

the dissolution of polymer can be thermodynamically described in 2 steps.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
