As the effective nuclear charge of an atom increases the atomic radii decreases and the ionization energy increases.
Effective nuclear charge is the net positive charge experienced by an single electron in an multi electron atom. The term “effective” is used because of the shielding effect of negatively charged electrons that prevents higher orbital electrons from experiencing the full nuclear charge.
So keeping this concept in mind we can say that as the effective nuclear charge on any atom increases the atomic radii or the size of the atom decreases. This is because as the the effective nuclear charge increases the electrons that are present in the orbit are pulled closer to the nucleus, so if the effective nuclear charge is more then the electrons are pulled more towards the nucleus and therefore the size or rhe atomic radii decreases
Now if we talk about the ionization energies, ionization energy is the energy required to remove the outer most electron from the orbit to form the ion. So if the effective nuclear charge is more for an atom then obviously the size of the atom would be less and because of this it will be difficult to remove the outermost electron as it is strongly attracted towards the nucleus. Hence the ionization energy will be more.

Answer: 1: 2
Carbon monoxide blocks oxygen in the blood. Hence, option A is correct.
<h3>What is combustion?</h3>
Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen.
During incomplete combustion part of the carbon is not completely oxidized producing carbon monoxide (CO). Incomplete combustion uses fuel inefficiently and carbon monoxide is released.
Carbon monoxide gas diffuses rapidly across the pulmonary capillary membrane, binding to haemoglobin with an affinity 200 times that of oxygen to form carboxyhemoglobin. By displacing oxygen, CO decreases the oxygen-carrying capacity and oxygen delivery to tissues, causing marked cellular hypoxia and acidosis.
Hence, option A is correct.
