QuestionIdentify the element symbol, number of protons, and electrons for an ion with mass number 65, 36 neutrons, and charge +1.
Studdy Solution
STEP 1
Assumptions1. The mass number of the ion is65. The ion has36 neutrons3. The charge of the ion is +1
STEP 2
First, we need to find the number of protons in the ion. The mass number of an atom or ion is the sum of its protons and neutrons. So, we can find the number of protons by subtracting the number of neutrons from the mass number.
STEP 3
Now, plug in the given values for the mass number and the number of neutrons to calculate the number of protons.
STEP 4
Calculate the number of protons.
STEP 5
The number of protons in an atom or ion determines its atomic number, and thus its identity as an element. The element with atomic number29 is copper (Cu).
STEP 6
Next, we need to find the number of electrons in the ion. In a neutral atom, the number of electrons equals the number of protons. However, in an ion, the number of electrons can be more or less than the number of protons, depending on whether the ion is negatively or positively charged. In a positively charged ion, there are fewer electrons than protons. The magnitude of the charge tells us how many more protons there are than electrons.
STEP 7
Now, plug in the given values for the number of protons and the charge to calculate the number of electrons.
STEP 8
Calculate the number of electrons.
The ion is a copper ion (Cu), with29 protons and28 electrons.
