Group 4a, period 2 element
Group 4a of the periodic table consists of the following elements:
1. Titanium (Ti)
2. Zirconium (Zr)
3. Hafnium (Hf)
These elements are located in the fourth column of the periodic table and belong to the transition metal group. They have similar properties, including high melting and boiling points, high strength, and good corrosion resistance. They are commonly used in various applications, such as aerospace industry, nuclear reactors, and medical devices.
The group 4A elements belong to the group 14 in the periodic table. Group 14 elements are also known as the carbon group elements. In period 2 of the periodic table, there are only two elements, namely:
1. Carbon (C) - Carbon is the 6th element in the periodic table with an atomic number of 6. It is a nonmetal and is highly versatile, forming the basis of all organic compounds. Carbon is found in various forms, including diamonds and graphite.
2. Silicon (Si) - Silicon is the 14th element in the periodic table with an atomic number of 14. It is a metalloid and is the second most abundant element on Earth, after oxygen. Silicon is widely used in electronics, as it is an excellent semiconductor.
These two elements, carbon and silicon, make up the group 4A elements in period 2.
