What are the properties of elements?
All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements.
What are the 3 kinds of elements and their properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
What are the properties of an element answer?
Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.
Why are different types of elements have different properties?
Because of this, an equal sized cube of titanium, iron, and copper may all have the same volume but will have different densities. Other properties of elements can be predicted from the periodic table as well including state of matter, reactivity, and conductivity. Different groups of elements have different properties.
These trends explain the periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity . The atomic radius of an element is half of the distance between the centers of two atoms of that element that are just touching each other.
What are the names of all the elements?

How are the properties of an element predicted?
The properties of elements, including but not limited to density and reactivity, can be predicted based on their arrangement in the periodic table. For example, as you move across a period, density usually increases. Because of this, an equal sized cube of titanium, iron, and copper may all have the same volume but will have different densities.
