An atom is the smallest representative particle of an element that still retains the chemical properties of that element. For example, a single atom of carbon is still carbon with all carbon's properties. If you cut that atom up any further, however, you no longer have carbon.
An element is substance composed of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means. For example, gold is an element can not be reduced any further. Only atoms will remain.
An atom is the smallest unit of an element, having all the characteristics of that element and consisting of a very small and dense nucleus containing protons and neutrons, surrounded by one or more shells of orbiting electrons.
If you take an atom of gold, and further divide it, you will no long have gold but those particles that make up the atom.
Elements are composed of only one kind of atom, determined by their atomic number which is the number of protons in the atom.
Molecules are composed of atoms of nonmetallic elements through covalent bonding.
An atom is the smallest particle of an element that can exist and have the properties of the element.
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
An element is composed of only one kind of atom. A compound is composed of two or more elements (kinds of atoms) chemically combined.
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
Yes, atoms make up almost everything, they can only be broken down into protons, neutrons and electrons. An element is a substance found on the periodic table with certain rules and regulations given to each element. An element is made up only of atoms. A compound is a mixture of two or more elements that can be broken down into elements again, it is not a pure substance as such. So a compound is made up of elements, elements are made of atoms.
atoms combine to form molecules of elements
They are related because atoms are made of matter,elements are made of atoms,and matter is made up of elements.
Atoms are related to elements because atoms are what comprise elements. An atom still has atoms no matter what state it is in.
Atoms are elements , e.g Hydrogen. Molecules are combinations of atoms, e.g water H2O is the combination of Hydrogen and Qxygen.
Elements and atoms are related because elements contain only one type of atom.
Protons are the positive charge electrons in atoms that make up elements.
spectra of elements with multi-electron atoms
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.
These are the chemical properties.
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
number of valence electrons
Because the differences in atoms make different elements. Elements are multiple of similar atoms.
You do an experiment to gather this evidence and then develop a hypothesis to explain what you observe.
