I really do not know what the answer for this question is.
he properties of salts are different from the properties of elements that go into making them
Allotrope refers to different forms of an element that have different physical or chemical properties, such as graphite and diamond being allotropes of carbon.
An atom
Isotopes are atoms of the same element that have different numbers of neutrons in their nucleus, resulting in variations in atomic mass. This leads to isotopes having similar chemical properties but different physical properties, such as stability and radioactivity.
The number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element, essentially different numbers of protons mean change the element you are looking at and hence the properties and reactions of that element.
The members of this family have similar chemical properties.
[read this, if you don't think it sounds good, don't use it or if it does not make good sense do not use it but read it first . THANK YOU!] What i think the statement means by is that the properties of salts are formed when an element in the group under sodium or magnesium in the Periodic Table combines with an element under fluorine.
You mean the smallest particle of an element that still retains that element's properties. It is the atom. Even one atom of, say, carbon is still carbon. Cut it up any further and you no longer have carbon.
Copper is a chemical element, so it is considered a substance with distinct chemical properties, not a physical property. Its physical properties include being a solid at room temperature, having a distinct color and density, while its chemical properties include its ability to react with other substances and form different compounds.
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.
Salts are made of a combination of halogen atoms and alkali metal atoms. These atoms have specific properties. If they combine with other atoms, however, and they make salts, then these salts have different properties than the atoms that make them. For example, sodium chloride is probably the most famous salt. Sodium is a soft, reactive metal and chlorine is a greenish gas (which, if possible, is even more reactive than sodium), but sodium chloride is a white and extremely nonreactive solid.
