Unlocking the Answers: Solutions to the Atomic Math Challenge
Let’s dive headfirst into the atomic world. We’ll now provide the answers and detailed solutions to a variety of Atomic Math Challenge questions.
The Atom’s Identity
The Question
An atom of an element has 8 protons and 8 neutrons. What is the element’s atomic number, mass number, and what element is it?
The Answer
Atomic Number: 8, Mass Number: 16, Element: Oxygen (O)
The Solution
1. Atomic Number: The atomic number is defined as the number of protons in the nucleus of an atom. In this case, there are 8 protons. Therefore, the atomic number is 8.
2. Mass Number: The mass number is the total number of protons and neutrons in the nucleus. We are given that there are 8 protons and 8 neutrons, so the mass number is 8 + 8 = 16.
3. Element Identification: Using the periodic table, look for the element with an atomic number of 8. You will find that it is oxygen (O).
Isotopes and Their Mass
The Question
An element has two isotopes. Isotope A has a mass of 35 amu, and isotope B has a mass of 37 amu. If the average atomic mass of the element is 35.5 amu, which isotope is more abundant?
The Answer
Isotope A is more abundant.
The Solution
1. Understanding Average Atomic Mass: The average atomic mass is a weighted average of the masses of all isotopes of an element. This means that the abundance of each isotope affects the overall average.
2. Analyzing the Values: The average atomic mass (35.5 amu) is closer to the mass of isotope A (35 amu). This implies that isotope A contributes more to the average than isotope B.
3. Conclusion: Because the average atomic mass is closer to 35 amu, isotope A must be the more abundant isotope.
Electron Arrangement
The Question
How many electrons can fit in the first, second, and third electron shells of an atom?
The Answer
First shell: 2, Second shell: 8, Third shell: 8
The Solution
1. Electron Shells: Electrons orbit the nucleus in specific energy levels, also known as shells.
2. First Shell Capacity: The first shell, closest to the nucleus, can hold a maximum of 2 electrons.
3. Second Shell Capacity: The second shell can hold a maximum of 8 electrons.
4. Third Shell Capacity: The third shell can hold a maximum of 8 electrons (though in some cases, the third shell can hold more, but only after the fourth shell has started to fill with electrons).
Chemical Symbol Decoding
The Question
A certain element has the symbol “Cl.” It has an atomic number of a specific value. What is the name of the element, and what is its atomic number?
The Answer
Chlorine (Cl), Atomic Number: 17
The Solution
1. Element Identification: Using the periodic table, find the element with the symbol “Cl.” This will reveal the element is chlorine.
2. Finding the Atomic Number: The atomic number is the number above the element’s symbol in the periodic table. For chlorine, the atomic number is 17.
Balancing Chemical Equations
The Question
Balance the following chemical equation: H₂ + O₂ → H₂O
The Answer
2H₂ + O₂ → 2H₂O
The Solution
1. Understanding the Goal: Balancing a chemical equation ensures that the number of atoms of each element on the reactant side (left side) equals the number of atoms of each element on the product side (right side).
2. Start with Oxygen: On the reactant side, there are 2 oxygen atoms (O₂), and on the product side, there is only 1 oxygen atom (in H₂O). To balance the oxygen, place a “2” in front of the H₂O: H₂ + O₂ → 2H₂O.
3. Balance Hydrogen: Now, look at the hydrogen. On the product side (2H₂O) there are 4 hydrogen atoms. On the reactant side, there are only 2 hydrogen atoms. To balance hydrogen, place a “2” in front of the H₂: 2H₂ + O₂ → 2H₂O.
4. Check the Balance: Now, recount all atoms on both sides of the arrow to confirm all the elements have the same number of atoms on both sides.
