The factors that may be responsible for the ionization energy within a period is

The diameter of the atom decreases somewhat as electrons are added.
The attractive force of the nucleus increases

<u><em>Explanation</em></u>

ionization energy is the Electron shielding.

Generally there is increase of ionization across the period that is from the left to the right.

Across the period ( from left to right) the diameter of the atom decreases. This make it harder to remove an electron as you go across the period, thus ionization energy increase across the period ( from left to right).
The force of attraction of the nucleus increase across the period ( from left to right). This is due to increase in number of protons across the period.

What is the concentration of hydrogen ions in a solution with a pH of 2.36?

Viefleur [7K]

Answer:

Explanation:

$pH = - log[H {}^{ + } ] \\ 2.36 = - log[H {}^{ + } ] \\ [H {}^{ + } ] = {10}^{ - 2.36} \\ [H {}^{ + } ] = 4.37 \times {10}^{ - 3} \: M$

Use the given relationship to calculate the ionization energy of a thallium atom, given that radiation of 58.4 nm produces elect

Elenna [48]

The ionization energy is 1 × 10^-18 J

<h3>What is ionization energy?</h3>

The ionization energy is the energy required to remove an electron from an atom.

We have the following information;

wavelength of the photon = 58.4 nm

Speed of the electron = 2310 × 10^3 m/s

Since;

hv = I + 1/2mv^2

v = c/λ

hc/λ = I + 1/2mv^2

I = hc/λ - 1/2mv^2

I = (6.6 × 10^-34 × 3 × 10^8/58.4 × 10^-9) - (1/2 × 9.11 × 10^-31 × (2310 × 10^3)^2)

I = 1 × 10^-18 J

VLD [36.1K]

<h2>The required "option is b) potential energy".</h2>

Explanation:

The energy which is associated with the motion of the object is called kinetic energy.
The energy which is associated with the amount of heat released is known as thermal energy.
The energy which is released during a chemical reaction is known as chemical energy.

Therefore, option (a), (c), and (d) are incorrect.

The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
Hence, the correct option is potential energy.
