Consider the following atoms in which X represents the chemical symbol of the element:
¹⁶₈X ¹⁶₉X ¹⁸₁₀X ¹⁷₈X ¹⁸₈X
d. What atoms have the same number of neutrons?

검증된 단계별 안내

Step 1: Recall that the number of neutrons in an atom can be calculated using the formula:

n = A - Z

, where

A

is the mass number (superscript) and

Z

is the atomic number (subscript).

Step 2: For each atom, calculate the number of neutrons using the formula. For example, for

{¹⁶}^{₈} X

, the number of neutrons is

16 - 8

Step 3: Repeat the calculation for each atom:

{¹⁶}^{₉} X

{¹⁸}^{₁₀} X

{¹⁷}^{₈} X

, and

{¹⁸}^{₈} X

Step 4: Compare the calculated number of neutrons for each atom to identify which atoms have the same number of neutrons.

Step 5: Group the atoms with the same number of neutrons together and note the results. For example, if two atoms have the same neutron count, they belong to the same group.

주요 개념

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

Atomic Structure

Atoms consist of protons, neutrons, and electrons. The atomic number, represented by the subscript in the notation, indicates the number of protons, while the mass number, shown as a superscript, is the total number of protons and neutrons. Understanding atomic structure is essential for determining the number of neutrons in an atom.

Neutrons

Neutrons are neutral particles found in the nucleus of an atom. The number of neutrons can be calculated by subtracting the atomic number from the mass number. Identifying atoms with the same number of neutrons involves comparing their mass numbers, as atoms with different atomic numbers can still have the same neutron count.

Isotopes

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. This concept is crucial for understanding the question, as it allows for the identification of atoms that share the same neutron count despite differing in mass number. Recognizing isotopes helps in categorizing the given atoms based on their neutron composition.
