These models show the electron structures of two different nonmetal elements. Which element is likely more reactive, and why? O Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. Element 1 is more reactive because it has more clectrons in its valence shell and is farther to the right on the periodic table. Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons. Element 1 Element 2

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
