if the element is neutral, how many electrons are there in oxygen? *\nyour answer\n\nhow many neutrons are in aluminum - 27 *\nyour answer
Answer
Explanation:
Step1: Recall atomic number of oxygen
The atomic number of oxygen is 8. In a neutral atom, number of electrons = number of protons = atomic number. So, number of electrons in neutral oxygen is 8.
Step2: Recall atomic number and mass - number of aluminum - 27
The atomic number of aluminum (Al) is 13, and the mass - number of aluminum - 27 is 27. The formula for calculating the number of neutrons is $n = A - Z$, where $A$ is the mass - number and $Z$ is the atomic number. So, $n=27 - 13=14$.
Answer:
The number of electrons in neutral oxygen is 8. The number of neutrons in aluminum - 27 is 14.
