Group 1a because atom size decreases going left to right

Group 1A

As the atomic number of elements in Period 3 (Atomic number 11-18) increases, the atomic radius decreases. The atom with the largest atomic radius is Na which is located in the group 1.
This is because, the effect of increasing proton number is greater than that of the increasing effective nuclear charge; therefore, there is a greater nuclear attraction. The valence electrons are held closer towards the nucleus of the atom. As a result, the atomic radius decreases.

Show dipole dipole force of water and ethyll alcohol.​
Alexeev081 [22]

Answer:

Water: H2O --> [H+] + [OH-]

Ethyl alcohol: C2H5OH --> [C2H5O-] + [H+]

Explanation:

Dipole-dipole force is observed when an ionic compound ionizes (forms ions), revealing its slightly positive ion and slightly negatively ion.

The chemical formula of Water is H2O.

H2O --> [H+] + [OH-]

The chemical formula of ethyl alcohol is C2H5OH.

C2H5OH --> [C2H5O-] + [H+]

Note the positive and negative parts of both water and ethyl alcohol as expressed in the equations above.

Bond order of n2<br><br>bond order of N2 ​
snow_lady [41]

Answer:

The MO method for N2+ gives the bond order equal to 2.5. But first, we look at the diagram of molecular orbitals for N2 (the bond order for the nitrogen molecule is 3). the N2+ molecule). That is, the bond order for N2+ is 2.5.
