Chemical elements are atoms all with the same number of protons and electrons. All atoms with only one proton are hydrogen. All atoms with two protons are helium and so forth. A molecule is two or more atoms joined together. Oxygen exists in the lower atmosphere as O2 (two oxygen atoms joined together) while in the upper atmosphere there is a layer of O3 (ozone or three oxygen atoms joined together). Chemical compounds are substances made of different atoms. Carbon dioxide for example exists as a CO2 This is also a molecule. Common salt is also chemical compound because it is made of Sodium and Chlorine but it forms a crystal structure rather than a molecule.

Who was the Russian chemist show a definite relationship between chemical properties and atomic weights of the elements?
Mendeleev
What is the relationship between zinc electronegativity and its chemical reactivity?
The relationship between zinc's electronegativity and its chemical reactivity is that zinc has a low electronegativity, which means it tends to lose electrons easily. This makes zinc more reactive in forming chemical bonds with other elements.
What relationship exists between elements and periods according to the periodic law?
The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
What is the relationship between the element symbols and triangles?
Element symbols are abbreviations used to represent chemical elements in the periodic table. Triangles are often used in chemistry to represent the relationship between elements in a compound, with each corner of the triangle representing an element involved in the compound.
How does electronegativity describe the relationship between an element's metallic character and its chemical properties?
Electronegativity is a measure of an element's ability to attract and hold onto electrons in a chemical bond. Elements with higher electronegativity tend to have non-metallic properties, while elements with lower electronegativity tend to have metallic properties. This relationship helps explain how elements interact with each other in chemical reactions.
Is the type of bonding between elements in a compound chemical-chemically?
Type of bonding between elements in a compound chemical-chemically is chemical bonding.
What is the relationship between elements and compounds and how can it be described?
Elements are the simplest form of matter, made up of only one type of atom. Compounds, on the other hand, are made up of two or more different types of atoms chemically bonded together. The relationship between elements and compounds can be described as elements combining to form compounds through chemical reactions.
What is the relationship between elements compounds of water?
Water is a compound made up of two elements: hydrogen and oxygen. Specifically, each water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, represented by the chemical formula H₂O. The properties of water, such as its polarity and ability to dissolve many substances, arise from the interactions between these elements within the compound. Thus, the relationship between the elements and the compound is foundational to the chemical and physical characteristics of water.
What expresses the relationship between elements in the compounds and the molecules they make up?
Chemical bonds, such as covalent bonds and ionic bonds, link elements together to form compounds. These compounds have distinct molecular structures based on the arrangement of their constituent atoms. The type and strength of the bond between elements influence the properties of the resulting molecules.
Why do you need electricity to make aluminim and titanium?
This is related to the chemical binding energy between the aluminum and other elements with which it is combined.This is related to the chemical binding energy between the aluminum and other elements with which it is combined.This is related to the chemical binding energy between the aluminum and other elements with which it is combined.This is related to the chemical binding energy between the aluminum and other elements with which it is combined.
What is the relationship between matter and elements?
A element cannot be broken down into simpler substances by physical or chemical means....A pure substance is made up of only one substance. So the relationship is they both have one substance -Ladiesman32-
What is the relationship between the molecules of elements and compounds in chemical reactions?
In chemical reactions, molecules of elements and compounds interact and rearrange to form new compounds. Elements are made up of single types of atoms, while compounds are made up of different types of atoms bonded together. During a chemical reaction, the bonds between atoms in molecules are broken and new bonds are formed, resulting in the creation of different compounds.
