Why is Palladium on the periodic table?
Palladium is a chemical element that is included in the periodic table because of its unique properties and atomic structure. It is classified as a transition metal and is known for its high corrosion resistance and catalytic properties.
Why is bromine classified as a p-block element?
Bromine is classified as a p-block element because its highest energy electrons are in the p orbital. This means it has electrons in its outermost electron shell which are involved in chemical reactions. Bromine is located in group 17 of the periodic table, known as the halogen group, which contains elements that exhibit similar chemical properties.
What is the difference in the modern periodic table and Mendeleev's table?
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
Can you find steel bronze and brass in the periodic table and why not?
Steel, bronze, and brass are not found in the periodic table because they are alloys, which are mixtures of two or more elements, with at least one being a metal. Steel is an alloy of iron and carbon, while bronze is an alloy of copper and tin, and brass is an alloy of copper and zinc. These alloys do not have individual entries in the periodic table because they are combinations of elements.
Should sulfur be classified as an element?
Yes, sulfur should be classified as an element because it is a pure substance made of atoms with the same number of protons in their nuclei. It cannot be broken down into simpler substances by chemical means.
Why are the substances on the periodic table classified as elements?
Substances on the periodic table are classified as elements because they are pure substances made up of only one type of atom. Each element has a unique chemical structure and properties that distinguish it from other elements.
Is a compound classified as a substance?
Yes, a compound is classified as a substance because it is made up of two or more different elements chemically bonded together. Substances can be classified as either elements or compounds based on their composition.
Why does carbon dioxide not appear on the periodic table?
Carbon dioxide is a compound composed of one carbon atom and two oxygen atoms. It does not appear on the periodic table because the periodic table lists elements, not compounds. Elements are substances that cannot be broken down into simpler substances by chemical means, while compounds are formed by the chemical combination of different elements.
Why is Palladium on the periodic table?
Palladium is a chemical element that is included in the periodic table because of its unique properties and atomic structure. It is classified as a transition metal and is known for its high corrosion resistance and catalytic properties.
Why doesn't sugar exist in the periodic table of elements?
Sugar is not found on the periodic table of elements because it is a compound made of carbon, hydrogen, and oxygen atoms. The periodic table only contains elements, which are substances made of a single type of atom, not compounds.
Which periatic table cannot be broken down into simpler substance?
The periodic table itself cannot be broken down into simpler substances because it is a tabular arrangement of all the known chemical elements. Each element on the periodic table is a fundamental substance that cannot be further broken down into simpler substances by ordinary chemical processes.
Where are elements listed and why compounds are not found there?
Elements are listed in the Periodic Table of Elements. Compounds are not listed there because they are not elements they are compounds. An element is a substance made up of one type of atom, compounds are formed from combinations of different elements.
Which pair is classified as chemical substances?
Water and salt are classified as chemical substances. Water is made up of hydrogen and oxygen molecules, while salt is made up of sodium and chloride ions. Both substances undergo chemical reactions to form new compounds.
Why isn't salt on the periodic table?
Air is a mixture of several gaseous elements, such as oxygen and nitrogen, and compounds, such as carbon dioxide. In the sense of the four elements, water, fire, earth, and air, air is an element.
Why is carbon dioxide not found in the periodic table?
Carbon dioxide is a compound composed of carbon and oxygen atoms, so it is not listed as a single element on the periodic table. The periodic table only includes elements, which are substances that cannot be broken down into simpler substances by chemical means.
Why its called periodic table?
Because the elements progress in a periodic function.
What is the Most toxic substance know in periodic table?
Elements are in the periodic table not substances, the most reactive of those elements would be Fluorine because of its electronegativity.
