Here’s what I found:
It takes very little energy to remove that outermost electron from an alkali metal. Thus, alkali metals easily lose their outermost electron to become a +1 ion. ... In fact, as you go down the 1A column, the first ionization energies get lower and lower, making cesium the most easily ionized element on the periodic table.
So basically it’s because part of what makes alkali metals so reactive is that they have one electron in their outermost electron layer.
The answer is D. Non Metal
Hope this helped!
Answer: 1.90x10²³ atoms of O
Explanation: First convert the mass of O into moles:
5.06 g O x 1 mole O / 16 g O
= 0.32 moles O
Next use Avogadro's Number to find the number of atoms of O
0.32 moles O x 6.022x10²³ atoms O / 1 mole O
= 1.90x10²³ atoms O
What the first person said lol
