The chemical properties of matter are mainly determined by the electrons in the outermost orbital shell. The exceptions to this occur in e.g. the Lanthanides and the Actinides, where as a group, the outermost shell of each is equally filled, and it is the number of electrons in the next innermost shell that now comes into play. Hence their very similar chemistry.
Similar considerations apply to both the columns and the rows of the Periodic Table, where those the elements share somewhat similar properties.
Mendeleev, by arranging a set of cards, each representing one element and its properties, was able to arrange the cards to form his periodic table, and thus predict where new elements could be found. His predictions also pointed to where elements had been incorrectly placed.

What comes out of chemical reactions?
Chemical reactions can produce a variety of products, including gases, liquids, solids, or energy in the form of heat or light. The specific products depend on the reactants involved and the nature of the reaction.
What year did john Dalton comes up with the idea that each type of matter is made up of only one kind of atom?
John Dalton proposed his atomic theory in 1803, which included the idea that each type of matter is composed of one kind of atom. His work laid the foundation for modern chemistry by suggesting that atoms of different elements have distinct properties. Dalton's theory was instrumental in advancing the understanding of chemical composition and reactions.
What is the definition of chemical corrosion?
Chemical corrosion is the process of deterioration or destruction of a material due to a chemical reaction with its environment, leading to the loss of the material's properties or functionality. This often occurs when a material comes into contact with substances such as acids, bases, or salts, causing it to degrade over time.
Does the weight of matter come mostly from protons or electrons?
electron mass = 9.10938188 × 10-31 kilogramsproton mass = 1.67262158 × 10-27 kilogramsProton is a factor of 10^4 times the mass of an electron.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
Wh where does chemical energy come from?
Chemical energy comes from the breaking or forming of chemical bonds in molecules. When bonds break, energy is released, and when bonds form, energy is absorbed. This energy comes from the arrangement of atoms and their interactions within a molecule.
Why is water a chemical and how?
Water is a compound because 2 elements are chemically bonded together within each molecule of water there are 2 hydrogen atoms and 1 oxygen atom. Because this compound is the same, same properties, no matter where it comes from or how you get it, it is said to be a chemical. Its chemical properties such as how it reacts to other substances are always the same for pure water.
What are the major properties of soil?
The major properties of soil include texture, structure, acidity, organic matter content, fertility, and moisture content. These properties influence the soil's ability to support plant growth and provide nutrients, water, and oxygen to plants. Understanding these properties is essential for managing and maintaining healthy soils for agriculture and other uses.
Matter can be created during a chemical reaction?
No, matter is not created or destroyed in a chemical reaction. The total mass of the reactants before a reaction is equal to the total mass of the products after the reaction. This is known as the law of conservation of mass.
The chemical symbol of gold?
The chemical symbol of gold is Au, which comes from the Latin word "aurum." It is a precious metal known for its valuable properties such as resistance to corrosion and conductivity.
Properties seen when one substance changes to another are known as?
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
What is energy that comes from bonds within matter called?
It's called chemical energy, and it explains why some chemical reactions get hot and others get cold. The chemical energy locked up in gasoline is what allows your car to burn it and get enough power to move thousands of pounds of mass down the road. So, chemical energy is a force to be reckoned with!
The volume of matter comes mostly from its?
Both, while electrons make up the most of the shell that counts as volume for matter electrons still require protons to keep them in stable orbit. But in short yes it is the electrons. Alex PH
List three charactoristics properties of matter?
Matter are in four states. They are solid, liquid, gas and ionic ie plasma. In case of solid, the properties are many. Conductive both heat and electricity, elastic property. In case of liquid and gas, both named as fluid as both are capable of flowing, the following properties are common. Diffusion, viscosity. In case of liquid there comes surface tension, osmosis, the properties to be mentioned.
What comes out of chemical reactions?
Chemical reactions can produce a variety of products, including gases, liquids, solids, or energy in the form of heat or light. The specific products depend on the reactants involved and the nature of the reaction.
What is a form of energy that comes from chemical bonds?
One form of energy that comes from chemical bonds is chemical energy. This energy is stored in the bonds of molecules and is released when these bonds are broken during a chemical reaction. It is a common form of energy found in fuels like gasoline, food, and batteries.
Are red jocko pitbulls aggressive?
Pitbulls, no matter the bloodline, are mostly non agresive towards humans.
