Due to the 3. Gulf Stream
Answer: Option (a) is the correct answer.
Explanation:
Elements which are most electropositive or electronegative are the most reactive in nature. Therefore, they are active.
Elements of group 1 are also known as alkali metals. Elements of group 1 are lithium, sodium, potassium, rubidium, cesium, and francium.
All these are highly electropositive in nature and thus, are active. These are placed at the top left column of periodic table.
Thus, we can conclude that out of the given options, the most active metals on the periodic table are found on the lower left.
Explanation:
there are 8 atoms of hydrogen
Answer:
The elements become less reactive.
Explanation:
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 and reactivity increases because of greater electron affinity.
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. The electron affinity decreases because of shielding effect and thus atom become less reactive.
