What are the combinations attached groups, atoms, or lone pairs you can add to a central atom?

Hello your question is poorly written below is the well written question

Explore what molecules you can build From . What are the combinations attached groups, atoms, or lone pairs you can add to a central atom?

answer :

Explanation:

From molecular Geometry changes there are two groups to be considered here and they are group and lone pairs

The combinations that can be added to a central atom

when there are three ( 3 ) groups and a lone pair the shape of the molecule will be pyramidal but when the three ( 3 ) groups does not have any lone pair attached to it, the shape of the molecule will be trigonal planar

When there are two groups and  two lone pairs the shape of the molecule will be bent while when there are two groups without lone pairs the shape of the molecule will be linear
