Answer:
Sr²⁺
Explanation:
Krypton has 36 electrons and an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. An ion with a charge of 2+ and 36 electrons is Sr²⁺. Since it has the same amount of electrons, Sr²⁺ also has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.

They search and study plants and types of animals in the ocean.
Answer: The name of the
is Iodine tetrabromide and it is a covalent compound.
Explanation:
Inter-halogen compounds are compounds which composed of two different halogen atoms. For example ;
etc.
The naming is done by first writing the central atom symbol's name followed by the prefix corresponding to the number of atoms of another halogen atom like: Mono for 1, di ,for 2 tri for 3, tetra for 4 , penta for 5 etc. After this name of the another halogen is written with suffix 'ide' in the end.
The name of the
is Iodine tetra bromide.
In halogen compounds, the difference in electronegativities is not so large due to which they form covalent compounds by the means of sharing the electrons. Hence the Iodine tetrabromide covalent compound.
