PLEASE HELP ME I DO NOT UNDERSTAND THIS Use the periodic table to compare the sizes of ionic radii with the corresponding atomic radii or other ionic radii. Choose from smaller and larger in the blanks below:

A sodium cation is a smaller or larger than a sodium atom.

A phosphorus anion is smaller or larger than a phosphorus atom.

A magnesium ion is smaller or larger than a sodium ion.

A chlorine ion is smaller or larger than a phosphorus ion.

A potassium ion is smaller or larger than a sodium ion.

answerleaving cheese out to get moldy;

(newtons first law)

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
