Question

see if you can complete the following table using only what is on this page. use the references to access important values if needed for this question. element symbol p atomic symbol li 7 3 atomic number n mass number 32 protons 3 neutrons 3 electrons 15 3 item attempts remaining try another version submit answer

Explanation:

Step1: Identify element from symbol

The symbol Li represents lithium.

Step2: Determine atomic number

The atomic number of lithium is 3.

Step3: Find number of protons

For a neutral atom, the number of protons is equal to the atomic number, so protons = 3.

Step4: Calculate neutrons

Mass number - Atomic number = Neutrons. Given mass number = 7 and atomic number = 3, so neutrons = 7 - 3 = 4.

Step5: Determine number of electrons

For a neutral atom, number of electrons = number of protons, so electrons = 3.

Answer:

Element	Symbol	Atomic Number	Mass Number	Protons	Neutrons	Electrons
