What else can I help you with?
Why are some elements reactive and some nonreactive - does it correlate with where they are on the table?
No it does not help with where the elements are located. Elements on the Periodic Table are organized by columns. If 2 elements are in the samecolumn they both have similar properties.
What does grouping on the periodic table of elements have to do with reactivity?
Grouping describes the behavior of elements. Different groups have different properties.
Why Mendeleev's used hydrides and oxides for classification of elements?
Mendeleev used hydrides and oxides for the classification of elements because these compounds exhibit systematic trends in properties that correlate with the atomic weights of the elements. By analyzing the properties of hydrides and oxides, he could identify patterns in reactivity, molecular structure, and oxidation states, which helped him establish a coherent arrangement of elements in his periodic table. This approach allowed Mendeleev to predict the existence and properties of undiscovered elements, reinforcing the periodic law.
An elements properties can be predicted from its?
An element's properties can be predicted from its position on the periodic table, specifically its atomic number and electron configuration. These characteristics influence an element's chemical and physical properties, such as reactivity, conductivity, and melting point.
What does a periodic table predict?
A periodic table predicts the properties and behavior of elements based on their atomic structure, such as atomic number, electron configuration, and chemical reactivity. It can be used to determine trends in properties like atomic size, electronegativity, and reactivity, aiding in understanding and predicting the behavior of elements in chemical reactions.

Why are elements put into families?
Elements are organized into families on the periodic table based on their similar chemical properties. Elements in the same family have the same number of valence electrons, which determines their reactivity and chemical behavior. This organization helps scientists predict the properties of unknown elements based on their location in the periodic table.

What is defined as a table of elements listed in order of chemical reactivity?
Periodic Table - Or Table of Reactivty
An elements properties can be predicted from its?
An element's properties can be predicted from its position on the periodic table, specifically its atomic number and electron configuration. These characteristics influence an element's chemical and physical properties, such as reactivity, conductivity, and melting point.
How can a periodic table entry for an element tell important information about the element?
Periodic table describes chemical properties of element.It can also describe its degree of reactivity.

The periodic table arranges elements by increasing .?
mass
Is the reactivity of the metal elements generally increase as you move from left to right across the periodic table true or false?
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
How did the periodic table get its name?
Based on the periodicity of the elements regarding properties, reactivity, valence electrons, etc.
What happens if the atomic mass of elements in the periodic table increase?
If the atomic mass of elements in the periodic table increases, it means the number of protons and neutrons in the atomic nucleus has increased. This can affect the element's chemical properties, such as reactivity and stability. Elements with higher atomic masses tend to be less common in nature and are often radioactive.
