Boron would have the lower first ionization energy.
Be: 1s2 2s2
B: 1s2 2s2 2p1 -> electron from the p orbital is easier to eject than than electron from the s orbital.

Inert gases are also called noble gases. They are the elements found in Group 8A in the periodic table. They are inert because they don't react with other elements. This is because they have the most stable electronic configuration. That's why elements form ions to gain or give way electrons so that they conform with the electronic configuration of the nearest inert gas. Basing on the periodic table, the nearest inert gas to K is Argon. The nearest inert gas to I is Xenon.

Answer:

a. Expansion: the spatial dilation of a material that occurs upon changes in its composition. (an increase in number or amount to become larger in size.)

E.g- in a thermometer, when it gets hotter, the liquid inside them expands and rises up the tube.

b. Sublimation: the process in which a solid changes directly into a liquid.

E.g- dry ice, solid iodine and ammonium salts.

when the above solids are heated, only particles which are found on the surface of the solid have enough energy to break all forces of attraction and form a gas.

c. Contraction: it is the opposite of expansion. when a liquid is cooled the particles slow down and contract.

E.g- when a thermometer is taken out of your mouth, it contracts and the liquid inside falls back to the bottom.

f. Random Motion: motion in which the particle moves in a zig-zag manner and not in a straight line. The kinetic particle theory states that matter is made up of particles which are in constant <em>random motion,</em>
