Why does an increase in the number of protons in the nucleus of an atom
increase the ionization energy of atoms within a period?

As you move left to right, reactivity gets lowered-protons gets increased which results in more attraction therefore less reactivity .

Explanation:

Ionization energy gets increased while going across through a period as the number of protons gets increased, therefore there is more attraction to the nucleus. The more attraction to the nucleus requires the huge energy for the valence e- to be removed.

While moving left to right, reactivity drops - increase in protons therefore more attraction therefore less reactivity .

As you go across, the nuclear charge increases so there is a stronger attraction for electrons therefore it is harder to lose electrons so reactivity decreases.

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

explanation:

and the person below goggled it.

mark as brainliest

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
