If you mean the chemical elements, what distinguishes one element from another is the number of protons. For example, hydrogen has 1 proton, helium has 2, etc. The number of neutrons may vary; the number of electrons is equal to the number of protons, but only in a neutral atom.
What else can I help you with?
What element is named after Russia?
I don't think there is any element named after Russia.
The simplest form of pure matter?
The most chemically simple form of pure matter is that of a pure element, not chemically bonded in any way.
How many germs are on your hand at any given time?
There are approximately 5,000 germs on your hand at any given time
How many germs are there on a hand at any given time?
At any given time, a human hand may contain as many as 5,000 germs.
Which element has the greatest metallic character?
Metallic character increases as one transitions down and right through the periodic table. By definition, francium (Fr) would be the most metallic, but only extremely small amounts of it exist at any given time, thereby rendering caesium (Cs) as the most metallic element.
Is reactivity a characteristic property?
Yes, it is a characteristic property for any element or compound.

Which element is not placed into any because of its unique properties?
Hydrogen is the element with unique properties that doesn't fit in any group.
What element is not placed in any group because of its unique properties?
Hydrogen is the element with unique properties that doesn't fit in any group.
Which characteristic is necessary to achieve a line spectra for any given element A.Excited gaseous element in a pressurized tube B.Applied high voltage C.Light passed through a prism D.All?
D. All of the above
Is unique for any given elements?
migration
What is the most notable characteristic of birds which is not found in any other animals?
Feathers - the only outwardly obvious characteristic unique to birds.
Are melting point unique to elements?
Yes, the melting point of a substance is unique and specific to that substance. It is the temperature at which a solid material changes into a liquid at atmospheric pressure. Each element or compound has its own distinct melting point.
What is a unique characteristic of Saturn?
spins faster than any other planet exept jupiter
What is an apomorphy?
An apomorphy is a derived characteristic of a clade - any feature which is unique to a base species and its descendants.
Why do we say atomic spectra are like finger prints of the elements?
Atomic spectra are unique for each element because they correspond to the energy levels of electrons in that element's atoms. When these electrons move between energy levels, they emit photons at specific wavelengths, creating a characteristic spectral pattern for each element. This unique pattern is analogous to a fingerprint, as it can be used to identify and differentiate elements.
What is always the same for any given element?
The number of protons.
