Answer 1

Answer:

Positively Charged

Explanation:

The is a group XVI and period 4 element of the periodic table with similar physical and chemical to that of tellurium and sulfur. Selenium exist in different allotropic forms, which have different solubility including selenate, selenite and selenium in elemental form

The Se ion in selenate has a positive charge of +6, while the selenate ion has a charge of -2

The Se ion in selenite has a charge of +4, while the selenite ion has a negative charge of -2.

The charge of Se in elemental selenium is 0.
