Identify each of the following: c. 1 0 X

Welcome back everyone. We need to determine what X would be in the following atomic symbol where we have zero in our left hand exponent zero in our left hand subscript. And then the chemical symbol as X for choice A, it states that X is a neutron for choice B it states that X is a gamma particle for choice C, it states that X is X is an electron. Sorry. And in choice D it states that X is a positron. So let's highlight our given symbol in a larger format. So we have X, we have in our left hand exponent zero and in our left hand subscript zero. Let's recall that the X represents our element symbol. Whereas the left hand exponent integer represents our mass number which is in shorthand expressed by the simple capital A. So in this case, we would say A is equal to zero. Next we have in the left hand subscript, our atomic number, which we should recall is represented by the symbol Z. So in this case, Z is equal to zero. Recall that our atomic number tells us our number of protons. So we would have zero protons for our given symbol. And recall that our mass number is calculated by taking the sum between our number of protons plus our number of neutrons. Now we want to recall a certain fact from our textbooks which is in reference to our gamma particle. So we recall that in our textbooks, the gamma particle has zero protons and a mass number equal to zero. Recall that our symbol for a gamma particle has zero as our mass number in the left hand exponent zero as our atomic number in the left hand subscript and the Greek symbol gamma, which is a Y looking symbol. So with this symbol outlined and this understanding of a gamma particle and its number of protons and mass number of zero, we would confirm that choice A which dates neutron, we can rule out, we can also rule out choice C which states electron and choice D which dates positron. And this leaves us with choice B which states that X in the following atomic symbol with a mass number of zero, an atomic number of zero corresponds to a gamma particle. So B is our final answer. I hope this makes sense. And let us know if you have any questions.

Textbook Question

Identify each of the following:
c. ¹₀X

Verified step by step guidance

Step 1: Understand the notation. The given symbol ¹₀X represents a nuclide in nuclear chemistry. The superscript (¹) is the mass number (A), which is the total number of protons and neutrons in the nucleus. The subscript (₀) is the atomic number (Z), which is the number of protons in the nucleus.

Step 2: Recall that the atomic number (Z) determines the identity of the element. Since the atomic number is 0, this does not correspond to any known element in the periodic table. Instead, this notation is often used to represent a particle, such as a neutron or other subatomic particle.

Step 3: Analyze the mass number (A). The mass number is 1, which suggests that the particle has a total mass equivalent to one proton or neutron. Since the atomic number is 0, this indicates that the particle has no protons and is likely a neutron.

Step 4: Conclude the identity of the particle. Based on the analysis, ¹₀X represents a neutron, which is a subatomic particle with a mass number of 1 and no charge (atomic number 0).

Step 5: Summarize the result. The symbol ¹₀X is used to denote a neutron, a neutral particle found in the nucleus of an atom.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Nuclear Notation

Nuclear notation is a way of representing atomic nuclei using the format A/Z X, where A is the mass number (total number of protons and neutrons), Z is the atomic number (number of protons), and X is the chemical symbol of the element. In the notation ¹₀X, the '1' represents the mass number, and '0' indicates the atomic number, which helps identify the specific isotope of the element.

Isotopes

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different mass numbers. For example, in the notation ¹₀X, the mass number of 1 suggests that this isotope has one proton and no neutrons, which is characteristic of a specific isotope of hydrogen known as protium.

Element Identification

Element identification involves determining the specific element represented by a given nuclear notation. In the case of ¹₀X, the atomic number '0' indicates that there are no protons, which corresponds to a theoretical particle rather than a conventional element. This highlights the importance of understanding both the mass number and atomic number in identifying elements and their isotopes.
