Plantae, as trees and flowers are examples of plants.
It can fit two more electrons within its valence shell to follow the octet rule. It will have a -2 charge to gain those two electrons to fill its octet.
Answer:
Sodium
Explanation:
The given elements are present in period three.
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 and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
Sodium is present at the start of period three so its atomic radius is greater while the smallest atomic radius will be of chlorine.
Answer:
In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
Explanation:
Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in.
The correct answer is D . Milk
