The species bonds with the most ionic character is the compound with elements that develop the higher electronegativity difference between each other.
the most ionic character had maximum EN.
EN is max for SiO2
hope this help
Answer:
I learnt this from Khan academy you should try it too
Explanation:
Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
Educated Guess Here!
Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
I think it’s C because those elements tend to gain electrons while the deepest shade of green tend to give electrons
