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.
<span>The scientific knowledge that
was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
Answer:
The answer is D
Explanation:
All of these solutions are correct.
Answer:
Liquid
Explanation:
Earth’s core is liquid because it’s hot enough to melt iron, but only in places where the pressure is low enough
<span>Good Morning!
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.
