8.5C 8. Element R and Element Q have the same number of valence electrons. These elements both have similar
chemical behavior, but Element Q has more energy levels than Element R.

i.e belongs to same group because of valence electrons are same

Explanation:

so it has same chemical behaviour. and q has more energy than r ionisation energy decreases from top to bottom

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
