검증된 단계별 안내

Step 1: Identify the elements in Group 5A (15) of the periodic table. These elements are nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).

Step 2: For part (a), consider which Group 5A element is a component of bones and teeth. Recall that bones and teeth contain calcium phosphate, which includes phosphorus.

Step 3: For part (c), determine which Group 5A element is the most abundant in the atmosphere. Remember that nitrogen gas (N2) makes up about 78% of the Earth's atmosphere.

Step 4: For part (d), identify which Group 5A element forms a basic oxide. Basic oxides are typically formed by metals, so consider the metallic elements in Group 5A, such as bismuth (Bi), which forms bismuth(III) oxide (Bi2O3).

Step 5: Review your answers to ensure they align with the descriptions provided, using your knowledge of the properties and occurrences of Group 5A elements.

주요 개념

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

Group 5A Elements

Group 5A elements, also known as Group 15 in the periodic table, include nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). These elements share similar chemical properties due to their valence electron configuration, which influences their reactivity and the types of compounds they form.

Phosphorus in Biological Systems

Phosphorus is a key component of bones and teeth, primarily found in the form of calcium phosphate. This mineral is essential for structural integrity and plays a critical role in biological processes, including energy transfer through ATP and the formation of DNA and RNA.

Nitrogen as an Atmospheric Element

Nitrogen is the most abundant element in the Earth's atmosphere, making up about 78% by volume. It exists primarily as a diatomic molecule (N2) and is relatively inert, playing a crucial role in the nitrogen cycle and serving as a key component in various biological and chemical processes.
