Answer:
Models 1 and 2 would be in the same group.
Explanation:
They have the same amount of valence electrons. Valence electrons are electrons in the outermost electron cloud. This means they have the same properties, therefore are in the same Group on the periodic table.
The number of valence electrons in 
will be 26.
The atom's outermost inhabited shell is where valence electrons are found. They are significant because they have a major impact on how an atom's chemical characteristics are determined.
The number of valence electron in P in 5 and number of valence electron in Cl is 7. There are one molecule of P and three molecule of Cl in molecule. By adding all valence electrons , the total number of valance electrons will be 26.
The Lewis structure of is shown as:
Therefore, the number of valence electrons in will be 26.

Answer:
The valence electrons in the metal atom in the lattice structure can delocalize and move freely. The electrons are "loosely" connected with their parent atom in the metallic bond because most metals have excess electrons in their outer orbitals above the stable configuration.
Explanation:
Says google
Inter molecula force
1- hydrogen bond
2- ion bond
3- dipole dipole
4- dipole bond or van der wael
but not all dipole dipole has the same strength
Isn't that a substitution reaction? Sorry if i am wrong haven't taken these in a while
