Answer:

Krypton

Explanation:

When Selenium forms an ion, it is trying to become krypton which is a noble gas.

Selenium belongs to the oxygen group on the periodic table. In this group, the atoms prefers to gain two electrons to complete their octet. When selenium gains two electrons, its octet is complete.

This will make the atom resemble krypton on the periodic table of elements.

This structure which is an octet confers a special stability on the element.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of

lianna [129]

Answer:

DECREASE BY A FACTOR OF FOUR

Explanation:

Using pressure equation:

P 1 / T1 = P2 /T2 (at constant volume)

P1 = P

T1 =T

P2 = ?

T2 = 4 T

So therefore;

P2 = P1T1/ T2

P2 = P T/ 4 T

P2 = 1/4 P

The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.
