Question

question 4 (1 point) build a lithium atom with the following symbol and fill in the table below it. 6 3 li name lithium - ______ number of protons ____ number of neutrons ____ mass ____ natural abundance ______ % stable? stable blank 1: blank 2: blank 3: blank 4: blank 5:

Explanation:

Step1: Identify isotope name

The notation $_{3}^{6}Li$ represents lithium - 6.

Step2: Determine number of protons

The atomic number (sub - script) is 3, so the number of protons is 3.

Step3: Calculate number of neutrons

The mass number (super - script) is 6. Number of neutrons = Mass number - Number of protons. So, $6 - 3=3$.

Step4: Determine mass

The mass number is 6, so the mass is approximately 6 atomic mass units.

Step5: Find natural abundance

The natural abundance of lithium - 6 is about 7.5 %.

Answer:

Blank 1: 6
Blank 2: 3
Blank 3: 3
Blank 4: 6
Blank 5: 7.5
