The ionizatin energy is the is the energy required to remove one electron from from a gaseous atom.
There is a clear trend for the first ionization energies (the ionization energy to remove the first electron) of the atoms.
Inside a group (a column of the periodic table) the ionization energy increases downwards .
Then, the element that has the greatest atomic number in the group has the highest ionization energy (it is more difficult to form its ion).
As per this trend, in the group 4A lead, Pb (atomic number 82) is the natural element with the highest ionization energy. But there is one artificial element in this group, whose atomic number is 114. It is called Flerovium and as per the rule it shall have a higher ionization energy.
Answer:
i think it is 1.27 x1024
Explanation:
i don't really know though
Answer:
An increase in temperature lead to more effective collisions between reactant particles
increase in the rate of a chemical reaction because the number of molecules with sufficient energy to react increases.
Explanation:
Answer:
The metallic elements have more metallic characteristcis.
Explanation:
- Metallic character is the name given to a set of common properties shared by the metallic elements.
- Metallic luster, high density, high electric and thermal conductivity are some physical properties associated with metallic characters.
- Malleability and ductility is also an important metallic characteristic.
- Generally the metals are hard and dense.
- The elements on the left hand side of the periodic table show metallic characteristics except hydrogen.
It depends on which manner the formulae is being asked but the answer is: KNO3
