A member of the alkali metal family whose most stable ion contains 86 electrons?

Answer 1

Oh, dude, you're talking about good ol' radium! It's like the bad boy of the alkali metal family with its 86 electrons in the most stable ion. Just picture it hanging out with its electron crew, causing trouble and being all unstable and stuff.

Answer 2

The alkali metal family includes elements in Group 1 of the Periodic Table, such as lithium, sodium, potassium, rubidium, cesium, and francium. These elements typically lose one electron to form a +1 cation. To determine which alkali metal has an ion with 86 electrons, we need to find the element that has 87 electrons in its neutral state. This element is francium (Fr), which has 87 electrons in its neutral state and forms a +1 cation with 86 electrons.

Answer 3

The alkali metals are in Group 1 of the periodic table. An element with 86 electrons in its most stable ion would be part of the fourth period of the periodic table. Considering this information, the member of the alkali metal family that fits these criteria is cesium (Cs).

Answer 4

Well, honey, you're looking for radium (Ra). It's a member of the alkali metal family and its most stable ion contains 86 electrons. So, there you have it, radium is your sassy answer.

Answer 5

Rubidium

Contains 37 protons and neutrons so it would Rb-

Answer 6

Potassium (K ' Kalium) . It is No. 19 in the Periodic Table, so it has 19 protons and 19 electrons. It has an Atomic Mass of 39. This means it has 39 - 19 = 20 neutrons.
