Explanation:
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.

Explanation:
The atomic radius is taken as the half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements. It is also the half - distance between two nuclei in the solid state of metals.
Across a period on the periodic table, atomic radii decreases due to increase in the nuclear charge without an attendant increase in the number of electronic shells.
Down a group atomic radii increases due to successive shells of electrons being added.
a. Al or B : down a group III, so aluminium is larger
b. Na or AI
: across a period so Na is larger
c. S or o
: down group VI so sulfur is larger
d. O or F
: across a period so oxygen is larger
e. Br or CI
: down a group VII so Br is larger
f. Mg or Ca: down a group II so Ca is larger
