It has more than one valence electron.
The quality that differentiates hydrogen (H) from the other elements in Group 1, the alkali metals, is that it is not very reactive.
The quality that differentiates hydrogen (H) from the other elements in group 1, the alkali metals, is that it is found by itself in nature. To determine this, we can look at the periodic table or refer to the periodic trends.
First, let's look at the periodic table. Group 1, also known as the alkali metals, includes elements such as lithium (Li), sodium (Na), potassium (K), and so on. These elements are usually found in nature as compounds rather than in their pure form. However, hydrogen (H) is an exception. It is usually found as a diatomic gas (H2) and does not commonly form ionic compounds like the alkali metals.
Alternatively, we can also refer to the periodic trends. The alkali metals in group 1 are known for having a single valence electron and being highly reactive. They readily lose this valence electron to form positive ions. On the other hand, hydrogen is a non-metal and does not have the characteristic of being highly reactive or having a single valence electron like the alkali metals. Therefore, hydrogen's nature of being found by itself in nature sets it apart from the alkali metals in group 1.
