Answer:
The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. ... If the cliff is high enough, the acceleration due to gravity and the air resistance due to the velocity will be exactly equal and there will be no change in kinetic energy.
Explanation:
<span>So atomic mass is not a natural way to order a periodic table, since periodic tables were (and are) principally aimed at capturing the chemical relationships between elements.</span>
Answer: 1. Conductor
2. Specific heat capacity
3. Radiation
Explanation:
The reason why Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.
In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.
Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.
Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than I.
