Determine whether each of the following statements is true or false. If false, correct the statement to make it true: (b) Every atom of a given element has the same number of protons.

검증된 단계별 안내

Identify the definition of an element: An element is defined by the number of protons in its atoms, which is known as the atomic number.

Understand that the atomic number is unique to each element and does not change. Therefore, every atom of a given element must have the same number of protons.

Recognize that while the number of protons remains constant for a given element, the number of neutrons can vary, leading to different isotopes of the same element.

Evaluate the statement: 'Every atom of a given element has the same number of protons.' This statement is true because the defining characteristic of an element is its number of protons.

Conclude that the statement is true and does not require correction.

주요 개념

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

Atomic Structure

Atoms are the basic units of matter, consisting of protons, neutrons, and electrons. The number of protons in an atom's nucleus defines the element and is known as the atomic number. For example, all carbon atoms have six protons, which distinguishes them from other elements.

Element Definition

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element is characterized by its unique number of protons, which determines its chemical properties and position in the periodic table. Thus, all atoms of a given element share the same number of protons.

True/False Statements in Science

In scientific reasoning, statements can be evaluated as true or false based on empirical evidence and established theories. A true statement accurately reflects scientific understanding, while a false statement may require correction. In this case, the statement about protons is true, as all atoms of a specific element indeed have the same number of protons.
