Nickel is classified as a transition metal, found in the middle of the periodic table. Unlike metalloids, it possesses all the traits of a true metal, such as high conductivity and malleability. While metalloids sit between metals and nonmetals, nickel is firmly in the metallic category due to its pronounced metal-like behavior.
Nickel is atomic number 28, positioned between cobalt (Co) and copper (Cu), both of which share similar properties with nickel. This placement highlights its role as a critical metal in the periodic table, bridging the gap between iron and copper.
Nickel is an excellent example of a metal in the periodic table. Its high melting point, ability to form strong alloys, and conductivity make it a prime example of a transition metal. It shares these characteristics with metals like iron and copper, both of which are essential in various industrial applications.
Nickel's magnetic properties also reinforce its classification as a metal. Unlike metalloids, nickel exhibits ferromagnetic properties, which means it can be magnetized under certain conditions. This property is often utilized in electronics and energy storage applications, adding to its versatility.
Nickel’s physical properties align closely with other metals. For example:
Iron: Like iron, nickel has high tensile strength and is magnetic at room temperature. This makes nickel a good substitute for iron in specific applications where additional corrosion resistance is needed.
Copper: Similar to copper, nickel is resistant to oxidation and corrosion, making it valuable in environments exposed to water or chemicals. Nickel and copper are often combined to form alloys like Monel, which is widely used in marine engineering.
Nickel’s ability to form durable alloys, especially with iron and copper, is a significant reason for its widespread use in steel production and other industrial applications. These properties make it essential in products that require both strength and resistance to environmental factors.

Nickel’s properties are starkly different from those of nonmetals. Nonmetals, such as sulfur and oxygen, are typically poor conductors of heat and electricity. This makes them ideal for use as insulators in electrical systems. Additionally, nonmetals tend to be brittle when solid, breaking easily under pressure, which contrasts with nickel’s durability and malleability. In comparison, nickel is an excellent conductor of both electricity and heat, similar to other metals like copper and aluminum. Furthermore, unlike nonmetals, which often lack the ability to be shaped or molded, nickel is malleable and can be formed into wires, sheets, or other shapes without losing its structural integrity. These fundamental differences make it clear that nickel shares none of the defining characteristics of nonmetals, reinforcing its classification as a metal.
Metalloids, often described as having properties of both metals and nonmetals, display semi-conductive abilities, which are especially useful in electronics and semiconductor technology. However, nickel does not exhibit these semi-conductive characteristics. Instead, nickel is a highly efficient conductor, similar to other metals such as iron and copper. Unlike metalloids, nickel has a distinct ability to form durable and strong alloys, such as those used in stainless steel. Additionally, nickel's ferromagnetic properties, which allow it to be magnetized, further differentiate it from metalloids like silicon and arsenic. While metalloids are commonly brittle and poor conductors, nickel is malleable, tough, and excellent at conducting energy. These significant differences solidify that nickel fits squarely into the metal category, not as a metalloid.
Nickel is undeniably classified as a metal. It exhibits all the hallmark traits of metals, including excellent electrical and thermal conductivity, malleability, and strength. As a transition metal, it seamlessly fits within the metallic group, sharing its key characteristics with other elements like iron, copper, and aluminum. Nickel's ability to form alloys, such as those used in stainless steel, enhances its value across industries. Its corrosion resistance and durability in harsh environments are additional traits that distinguish it as a metal. These attributes make nickel indispensable in various industrial applications, from manufacturing to electronics, confirming its place as a metal on the periodic table.
Despite its clear classification as a metal, nickel often sparks confusion due to its diverse range of applications and some of its less typical characteristics. For instance, nickel can be somewhat brittle under certain conditions, which is a trait more commonly associated with metalloids. This property, however, does not overshadow its overall metal-like behavior. The versatility of nickel—being both malleable and resistant to corrosion—further solidifies its classification as a metal. Some may mistake these occasional deviations as signs of a nonmetal or metalloid, but its overall physical and chemical properties align firmly with metals. Nickel’s superior conductivity and capacity to form strong, durable alloys make it a prime example of a transition metal.
Nickel is an essential metal with wide applications in manufacturing, aerospace, and energy.
