Answer:

Sodium

Explanation:

The given elements are present in period three.

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

Sodium is present at the start of period three so its atomic radius is greater while the smallest atomic radius will be of chlorine.

The number of π molecular orbitals in a molecule is always equal to the number of ________. a. p orbitals used to construct the
Dmitrij [34]

The number of π molecular orbitals in a molecule is always equal to the number of p orbitals used to construct the π bonds.

An electron's position and wave-like behavior within a molecule are described by a mathematical function called a molecular orbital. Chemical, as well as physical properties like the probability of locating an electron in a particular area, can be determined using this function.

A molecular orbital would be created when two atomic orbitals cross one other along the internuclear axis. A molecular orbital is created when two atomic orbitals cross each other sideways.

Therefore, the number of π molecular orbitals in a molecule is always equal to the number of p orbitals used to construct the π bonds.

Hence, the correct answer will be option (a).

How is the 2s orbital different than the 1s orbital? (Choose all that apply)
Irina-Kira [14]

The 2s orbital different than the 1s orbital because the 2s orbital extends farther from the nucleus than the 1s.

As we move away from the nucleus, the values of the principal quantum number (n) continues to increase.

As the principal quantum number (n) increases, the orbital becomes farther away from the nucleus.

The higher energy orbital are always larger than the orbitals closer to the nucleus.

Hence, the 2s orbital different than the 1s orbital because the 2s orbital extends farther from the nucleus than the 1s.
