Its nitrogen as its outer electron is closer to the nucleus so there will be a stronger electrostatic attraction between it and its nucleus

Answer: Nitrogen has the highest ionization energy.

Explanation:

Ionization energy is defined as the amount of energy required to remove an electron from an isolated gaseous atom.

X(g)\rightarrow X^+(g)+e^-

In a periodic table, ionization energy increases as we go from left to right in a period and decreases when we go down in a group.

Group 5A elements are Nitrogen, phosphorous, arsenic, Antimony and Bismuth.

So, the order of ionization energy in the group will be:

N>P>As>Sb>Bi

Hence, the nitrogen has the highest ionization energy.

Why would a student use rate laws in this investigation
Pani-rosa [81]
If you use rate laws then your answer will be more supported. Laws can not change, so if you use rate laws then the student will get a more accurate answer then if they don’t use rate laws.

II. Binding Forces A. Write a brief, one or two sentence, description of each binding force listed below. 1. London dispersion f
Leya [2.2K]

Answer:

All description is given in explanation.

Explanation:

Van der Waals forces:

It is the general term used to describe the attraction or repulsion between the molecules. Vander waals force consist of two types of forces:

1.  London dispersion forces

2.  Dipole-dipole forces

1. London dispersion forces:

These are the weakest intermolecular forces. These are the temporary because when the electrons of atoms come close together they create temporary dipole, one end of an atom where the electronic density is high is create negative pole while the other becomes positive . These forces are also called induce dipole- induce dipole interaction.

2.  Dipole-dipole forces:

These are attractive forces , present between the molecules that are permanently polar. They are present between the positive end of one polar molecules and the negative end of the other polar molecule.

Hydrogen bonding:

It is the electrostatic attraction present between the atoms which are chemically bonded. The one atom is hydrogen while the other electronegative atoms are oxygen, nitrogen or flourine. This is weaker than covalent and ionic bond.

Ionic bond or electrostatic attraction:

It is the electrostatic attraction present between the oppositely charged ions. This is formed when an atom loses its electron and create positive charge and other atom accept its electron and create negative charge.

Hydrophobic interaction:

It is the interaction between the water and hydrophobic material. The hydrophobic materials are long chain carbon containing compound. These or insoluble in water.

Covalent bond:

These compounds are formed by the sharing of electrons between the atoms of same elements are between the different element's atoms. The covalent bond is less stronger than ionic bond so require less energy to break as compared to the energy require to break the ionic bond.
