Answer:
A. the compound P4At8 is a covalent molecule and its name is Phosporus astatide
B. the compound MtN is an ionic molecule and its name is Meitnerium nitride.
Explanation:
The question requires us to name and classify the type of chemical bond for the compounds P4At8 and MtN.
To solve this problem, we need to keep in mind that an ionic bond is formed between metals and non-metals, while a covalent bond is usually formed between two non-metallic atoms.
The compound P4At8 is formed by the elements phosporus (P) and astatine (At), which are both non-metals:
Therefore, the compound P4At8 is a covalent molecule and its name is phosporus astatide.
The compound MtN is formed by the elements Meitnerium (Mt) and nitrogen (N), which are a metal and non-metal, respectively:
Therefore, the compound MtN is an ionic molecule and its name is Meitnerium nitride.
