Question
- using the symbol readout box, figure out which particles affect each component of the atomic symbol and how the value of the numbers is determined. position in symbol box term to describe this information particle used to determine this how the value is determined a b c d
Step1: Identify element symbol
The letter 'a' represents the chemical symbol of the element. It is determined by the type of atom, which is based on the number of protons.
Step2: Determine charge
'b' is the charge of the ion. It is determined by the number of electrons relative to the number of protons. If there are more electrons than protons, it is a negative - ion; if fewer, it is a positive - ion.
Step3: Identify atomic number
'c' is the atomic number, which is equal to the number of protons in the nucleus of the atom. Protons are the particles that determine the atomic number.
Step4: Identify mass number
'd' is the mass number, which is the sum of the number of protons and neutrons in the nucleus. Protons and neutrons together determine the mass number.
