Final answer:
Article II of the US Constitution contains language about the executive branch of government, outlining the President's responsibilities and powers.
Step-by-step explanation:
The article of the US Constitution that contains language about the executive branch of government is Article II. This area of the Constitution delineates the responsibilities and powers of the President. Article II is referred to as establishing the Executive Power, which implies that the role of the President includes being the head of the federal government, presiding over the administration of laws, and serving as Commander in Chief of the armed forces.
The placement of Article II after Article I, which outlines the Legislative Branch, might suggest a certain ranking or order of operations within the structure of the national government. In contrast, Article I details the Legislative Branch and Article III the Judicial Branch. Article IV addresses issues between states and federal-state relations, not the executive branch.
