How long does it usually take fir a rock to undergo a stage within the rock cycle

Thousands to Millions of Years

Explanation:

The rock cycle does not have just one proper direction, there are many pathways for rocks to travel through it. However, for most rocks to be changed from type to another will likely take anywhere from a few million to hundreds of millions of years.

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

yes
