1. Highly reactive: Group one elements, also known as alkali metals, are highly reactive due to their tendency to lose an electron to achieve a stable electron configuration. For example, sodium (Na) reacts violently with water to form sodium hydroxide and hydrogen gas.
2. Soft and malleable: Group one elements are soft and malleable, meaning they can be easily cut with a knife and shaped into different forms. For example, potassium (K) is a soft metal that can be easily cut with a knife.
3. Low melting and boiling points: Group one elements have low melting and boiling points compared to other metals. For example, lithium (Li) has a melting point of only 180.5°C and a boiling point of 1342°C.
4. Good conductors of heat and electricity: Group one elements are good conductors of heat and electricity due to the presence of free electrons that can move easily through the metal lattice. For example, rubidium (Rb) is used in atomic clocks due to its high electrical conductivity.
5. Form colored compounds: Group one elements can form colored compounds due to the presence of unpaired electrons in their outermost electron shell. For example, cesium (Cs) forms a variety of colored compounds, including cesium chloride which is used in the production of optical lenses.
