The atom positions in a general molecule of formula (not shape class) AXn that has shape square pyramidal at the corers of square and one at the above center of the square.
<h3>What is square pyramidal?</h3>
The square pyramidal is a shape geometry of the hybridization in which it consists of one lone pair and 5 bond pairs of electrons that repel each other and due to which the geometry changes from octahedral to square pyramidal.
As atoms are located at the four corners of the planer and one atom at the above center of the planner which is repelled by 4 atoms present at the corner of the planer.
Therefore, the atom positions in a general molecule of formula (not shape class) AXn that has a shape square pyramidal at the corners of the square and one at the above center of the square.

Answer:
4) They are substances.
Explanation:
Compounds are substances that are made up of two or more kind of atoms that are chemically bonded together.
The properties of a compound is distinct and different from those of the individual elements that combines to make it up.
What then is a substance?
Any matter be it solid, liquid or gas with a specific composition is a substance. For example, NaCl is common salt and its chemical properties are uniform in all parts but sea water is not a substance as it is made up of water, mineral salts, dissolved gases etc.
Answer:
Formation of a dative bond or coordinate bond between ammonia and boron trifluoride. When the nitrogen donates a pair of electrons to share with the boron, the boron gains an octet. Both atoms are electronically saturated.
