Q: Which group of metals in the periodic table include elements such as sodium and potassium? Read this paragraph and choose the correct option from the provided answers: The first step in the process of inductive reasoning is making specific observations. In the periodic table of elements, which we will discuss later, there is a group of metals with similar properties called the alkali metals. The alkali metals include elements such as sodium and potassium. If I put sodium or potassium in water, I will observe a very violent reaction every time. I draw a general conclusion from these observations: all alkali metals will react violently with water. Choices: - igneous metals - actinides - lanthanides - alkali metals A:
alkali metals
