Iodine electron configuration is:

1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 5S^2 4d^10 5P^5
when Krypton is the noble gas in the row above iodine in the periodic table,
we can change 1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 by the symbol
[Kr] of Krypton.

So we can write the electron configuration of Iodine:
[Kr] 5S^2 4d^10 5P^5

[Kr]4d^10 5s^2 5p^5. This allows us to determine the shape and energy of the electrons of iodine. There are 3 rules in determining electronic configuration such as AUFBAU's principle,HUND's rule and PAULI EXCLUSION principle.

The density of Mg is 1.74g/cm3. The density of strontium is 2.60g/cm3. What would you expect the density of Ca to be?

Tomtit [17]

The density of Ca will be between that of Mg and Sr

Explanation:

Ca, Mg and Sr are group II elements. They are called alkali earth metals. The correct order of the elements in this group are: Be, Mg, Ca, Sr, Ba and Ra.

Density is an intensive property of matter which describes the amount of matter(mass) per volume of a substance.

Density varies proportionally with mass. The higher the mass, the higher its density.
On the periodic table, atomic mass which the number of protons and neutrons in the nucleus of an atom increases down the group.
This implies a progradation in the value of density down the group. Therefore one expects that the value of density of Ca will fall between that of Mg and Sr. It cannot be more than 2.6g/cm³ nor less than 1.74g/cm³.

Answer:

When a scientist on Earth drops a hammer and a feather at the same time an astronaut on the moon drops a hammer and a feather, the result expected is that the hammer hits the ground before the feather on Earth, and the hammer and feather hit at the same time on the moon (option D).

Explanation:

In the abscence of atmosphere (vacuum), the objects fall in free fall. This is, the only force acting on the objects is the gravitational pull, which is directed vertlcally downward.

Under such absecence of air, the equations that rules the motion are:

V = Vo + gt
d = Vo + gt² / 2
Vf² = Vo² + 2gd

As you see, all those equations are independent of the mass and shape of the object. This explains why when an astronaut on the moon drops a hammer and a feather at the same time, the hammer and feather hit at the same time on the moon, a space body where the gravitational attraction is so small (approximately 1/6 of the gravitational acceleration on Earth) that does not retain atmosphere.

On the other hand, the air (atmosphere) present in Earth will exert a considerable drag force on the feather (given its shape and small mass), slowing it down, whereas, the effect of the air on the hammer is almost neglectable. In general and as an approximation, the motion of the heavy bodies that fall near the surface is ruled by the free fall equations shown above, so, the result that is expected when a scientist on Earth drops a hammer and a feather at the same time is that the hammer hits the ground before the feather.
