The transformation is called sublimation.
sodium only has one valence electron meaning that there is only one electron in the outer rim. so it will go... 1st energy lvl=2 electrons. 2nd energy lvl=8 electrons. and, 3rd energy lvl=1 electron.
Explanation:
hope i helped.
If the number of electron is more than the protons,the atom is negative
if the number of electrons is less than the protons, the atom will be positive
Answer:
five half lives
Explanation:
Half-life is the time required for a quantity to reduce to half of its initial value.
How many half lives it would take to reach 3.13% form 100% of it's initial concentration:
100% - 50% : First Half life
50% - 25%: Second Half life
25% - 12.5%: Third Half life
12.5% - 6.25%: Fourth Half life
6.25% - 3.125%: Fifth Half life
This means it would take five half lives to get to 3.125% (≈ 3.13%) of it's original concentration.
