Answer:
Cs
Br
Ti
Explanation:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased. In this way atomic radii of Cs is larger than K and size of Br is larger than F.
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases
Thus size of As is smaller than Ti.
Answer:
“It's that loss of moisture from upper layers of the skin that causes it to dry out.” Winter air is often dry, and the air that comes out of indoor furnaces can be even worse. However, dry skin can make its mark at other times of the year, too.
Explanation:
On January 28, 1986, the NASA shuttle orbiter mission STS-51-L and the tenth flight of Space Shuttle Challenger (OV-99) broke apart 73 seconds into its flight, killing all seven crew members, which consisted of five NASA astronauts and two payload specialists.
Answer:
The answer is True
Explanation:
This is because they are equivalent and have same number of bit.
Molarity is a term that applies to the amount of Moles of solute, per each litre of the solution.
