Answer 2

i think Na.

Answer 3

Look at the periodic table. What do you know about atoms near the edge of the periodic table? They are only one electron away from having a complete octet, so they tend to gain or lose an electron in order to be more stable. So these atoms are really the most reactive, since they need another atom from which to take or give their electrons to.

Sodium is on the far left, meaning it just needs to lose its electron. Oxygen is all the way on the other end of the table, and super electronegative, meaning it loves electrons. It will happily take sodium's electron while kicking off a hydrogen.

The other elements you showed are all in the middle, and not very reactive. In fact, sodium will light on fire when thrown in water. Also, ever wonder why we use Lithium Ion batteries? Look where lithium is on the periodic table! Super reactive!

Answer 4

I dont know Bi, but i think Fe, Al and Na can all react with water. To be specific, Na can react with water very fiercely, so does Al with warm water(around 50`C) but very slowly. Fe can react with water vapor in form of powder!

Answer 5

Hmmm... so whats it between

Answer 6

If only you could read, you'd find that I told you the answer.

Answer 7

In reality, all of them will react, but at room temperature it's a negligible amount with rate constants incredibly tiny. You can perform all of these by adding heat. Don't be fooled.
