Answer 2

Chemical Bond Type and Molecular Structure

For the given chemical compounds, the type of chemical bond and molecular structure can be determined as follows:

1. BaY2+: - Chemical Bond Type: Ionic bond - Molecular Structure: The compound BaY2+ forms an ionic bond due to the transfer of electrons from Ba to Y, resulting in the formation of Ba2+ and Y2- ions.

2. F2: - Chemical Bond Type: Covalent bond - Molecular Structure: The compound F2 forms a covalent bond due to the sharing of electrons between the two fluorine atoms.

3. Ca: - Chemical Bond Type: Metallic bond - Molecular Structure: The element Ca exists as a metal and forms metallic bonds with other Ca atoms in a metallic lattice structure.

4. NH3: - Chemical Bond Type: Covalent bond - Molecular Structure: The compound NH3 forms covalent bonds between the nitrogen and hydrogen atoms, resulting in a trigonal pyramidal molecular structure.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
