The electron
Electrons play the greatest part in determining the properties of an element. The number of electrons in the outermost energy level (valence electrons) determines an element's chemical behavior, such as its reactivity and ability to form bonds with other elements.
When Mendeleev developed his periodic table, he placed the greatest emphasis on organizing the elements based on their atomic masses and grouping elements with similar properties together. He also left gaps for undiscovered elements and predicted their properties.
Electrons are the subatomic particles that play the greatest role in cellular chemical reactions. They are involved in forming bonds between atoms and participating in redox reactions that are essential for cellular metabolism.
Land feature and proximity to oceans has the greatest effect on determining the climate of a region.
All elements are similar in that they contain protons and neutrons 'fused' into their nucleus, surrounded by the same number of electrons as protons. They are grouped in the periodic table according to their physical properties, eg transition metals, inert gases, rare earth elements etc.
In chemistry all most all elements properties are known based on periodic table.
Dmitri Mendeleev's greatest triumph with the periodic table was his ability to predict the properties of undiscovered elements. Gaps in the table led him to propose the existence of new elements with specific characteristics, which were later discovered and matched his predictions, confirming the validity of his periodic law.
The greatest effect on determining the climate of a region is the temperature. Other factors that can be used include vegetation and land features among others.
By determining the individual slopes, and comparing.
Households
Electrons are the subatomic particles that play the greatest role in bonding because they are involved in the formation of chemical bonds between atoms. They determine the type of bond formed (ionic, covalent, or metallic) based on their interactions with other atoms.
