What is the half-life of sodium-24? EXPLAIN how you determined your answer.
liraira [26]
Half-life is basically how long it takes for a radioactive molecule to get to 1/2 of its original mass.

so if sodium 24 mass was 5g and it's half life was 24years then:

after every 24years 1/2 of 5g would have decayed. so in 48years there will only be 2.5g left.

How do electrons enter an orbital​
Hoochie [10]

Answer:

Electrons that occur together in an orbital are called an electron pair. An electron will always try to enter the orbital with the lowest energy. ... In other words, within one energy level, electrons will fill an s orbital before starting to fill p orbitals. The s subshell can hold 2 electrons.
