The Number of protons of an atom defines which element it is, for example an atom with three protons will always be Lithium
If it is an atom, not an ion, then the number of protons = no. of electrons
differing numbers of neutrons effect the Atomic Mass of an atom, differing atomic masses create isotopes, but they are still the same element?
what sets an atom of one element from atoms of all other elements
is the elements atomic number,
A lot of things.... Some examples: electronegativity, charge, radius/size, electron affinity, ionization energy, Zeff (Effective Nuclear Charge), reactivity (related to some things listed before), etc.
For an easy course (which I'm assuming you're in), you probably only need to know the first three.
The number of protons distinguishes one element from another.
The number of protons in the atomic nuclei.
Important is the number of protons in the nucleus; it is a typical characteristic.
the number of protons in the atom. No two elements have the same number of protons in their atoms.
An atom is distinguished for another by the # of protons.
the number of protons
These atoms are known as valence atoms.
I don't think there is another name for elements but you can say a subtance that contain one atom
An Element is the substance consisting of only one type of atom
There is one thing that distinguishes one animo acid from another. The only way to tell them apart is by the side chain.
By definition, an Element contains only one kind of atom - atoms of that element. If it has more than one kind, it is a compound, not an element.
the number of protons
What distinguishes atoms of one element, from atoms of another element, is the number of protons. For example, any atom that has 6 protons in its nucleus is a carbon atom.
atomic number of an atom is its own characteristic property,ie.the number of protons or electrons in an atom,which distinguishes atoms from one another
The number of protons in the atomic nuclei.
An element's atomic number, or number of protons, differentiates one element from another.
When an atom of one element is brought in contact with an atom of another element, electrons get transferred from one element to another. However, if the atoms of same element come together then electrons are shared and not transferred. Exception to this is elements in noble gases.
I do not know i am gust a kid and this is my homework.
It is the number of protons in the nucleus of an atom. It defines what element the atom is.
The number of protons in an atom determines the identity of the element.See these two related questions for more information:[http://wiki.answers.com/Q/What_is_the_atomic_number_and_what_does_it_tell_you_about_the_number_of_protons_in_an_atomWhat is the atomic number and what does it tell you about the number of protons in an atom?]and[http://wiki.answers.com/Q/How_do_you_find_the_number_of_protons_and_electrons_and_neutrons_in_an_atomHow do you find the number of protons and electrons and neutrons in an atom?]
A pure substance made of only one type of atom is an element.An element, or elementary substance.An element.
One element differs from another element by the number of protons in their atoms. The number of protons in the atom is known as the atomic number. Also one isotope of an element differs from another isotope of the same element by the number of neutrons in their atoms.
The atomic number or z number or the number of protons is what makes one atom different from another. The atomic number or z number or the number of protons is what makes one atom different from another.
