Consider an atom of 10B. (c) What is the symbol of the atom obtained by adding one neutron to 10B?

검증된 단계별 안내
1
Step 1: Understand the atomic structure. The atomic number (Z) of an atom is the number of protons in its nucleus, and the mass number (A) is the sum of the number of protons and neutrons. The symbol for an atom is usually written as ^A_ZX, where X is the chemical symbol, Z is the atomic number, and A is the mass number.
Step 2: Identify the atomic number and mass number of the given atom. For 10B, the atomic number (Z) is 5 (since Boron's atomic number is 5) and the mass number (A) is 10.
Step 3: Understand the effect of adding a neutron. Adding a neutron to an atom increases its mass number by 1, but does not change its atomic number (since the number of protons remains the same).
Step 4: Calculate the new mass number. Since we are adding one neutron to 10B, the new mass number will be 10 + 1 = 11.
Step 5: Write the symbol for the new atom. Since the atomic number remains the same (5 for Boron), and the mass number is now 11, the symbol for the new atom is 11B.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Atomic Structure

Atoms consist of protons, neutrons, and electrons. The number of protons defines the element, while the total number of protons and neutrons gives the atomic mass. In the case of boron-10 (10B), it has 5 protons and 5 neutrons, making it a specific isotope of boron.

Atom Structure

Isotopes

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. This difference in neutrons results in different atomic masses. For example, adding one neutron to 10B creates 11B, which is another isotope of boron.

Nuclear Notation

Nuclear notation is a way to represent isotopes using the element's symbol, the atomic number (number of protons), and the mass number (total number of protons and neutrons). For boron-10, the notation is 10B, and after adding a neutron, the notation for the new isotope becomes 11B.
