Has largerst ionization energy in its period?
Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.
How does ionization enthalpy vary as you move across the periods vary from left to right?
in a period size decreases from left to right and hence electrons are more tightly held to the nucleus. so electron gain enthalpy increases across a period . down the period size increases and thus in general electron gain enthalpy decreses .
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
What do period members have in common in the periodic table?
There are seven periods in the periodic table--represented by seven horizontal groups. Each group is organized in such a way that is meant to illustrate similar chemical behavior in the elements. For instance, period 2 elements obey the ocet rule, which means that they need 8 electrons to complete (or stabilize) their valance shell.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.

Which element has the highest ionization rate Sodium aluminum calcium or phosphorus?
phosphorous has highest ionization enthalpy because along the period ionization will increase.
Which element pf the 4th period has highest ionisation energy?
krypton because it is an inert/noble gas, which means it has a complete outer shell and takes a lot of energy to remove an electron.
What happens to the first ionisation energy of the elements as a period is crossed?
tinger tinger tales
Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential

What trend in ionization energy occurs going across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
What element deviates from the trend in ionisation energy across period 2?
boron electros removed from 2p orbitals more shielded from the + nucleus so easily lost
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
