What information you can learn about an element from its atomic number?

Of course if you know the atomic number of an element you can look up the name of the element and then find out everything there is to know about that element and its compounds from various reference works. But I don't think that's what you're asking.
If you know the atomic number then you know the number of protons in the element's atom's nuclei. More importantly, from the standpoint of chemisty, you know the number of electrons in each atom. This is not especially interesting in itself. However, given a knowledge of how electrons arrange themselves in orbitsor shells it is possible to work out how an atom will be most likely to interact with other atoms chemically. In essence the Periodic Table offers a summary.

What can we learn about an Atom of an element if it's atomic number is known?
The number of protons in its nucleus, the number of electrons it has and its name.
How do you find the neutrons of an element using only the atomic number?
You can't. You can narrow it down a bit---most stable elements have a neutron-to-proton ratio of between 1.5:1 and 1:1 (depending on size). So if you know how many neutrons an element has you can make an educated guess as to approximately how many protons it will have. However, it is impossible to know exactly how many protons an element has based on its number of neutrons, and since the number of protons determines the element's identity, you cannot learn an element's identity from its number of neutrons. For example---all of the following isotopes can be formed with 7 neutrons, with stable ones bolded and underlined: He-9, Li-10, Be-11, B-12, C-13, N-14, O-15, F-16, Ne-17, Na-18, and Mg-19.
How do you learn atomic masses and atomic number?
You would either have to look them up in a periodic table, internet (eg. wikipedia) or in a manual, or you'd have to learn them by head, like you do with telephone numbers.
Imagine you are a scientist who has just discovered a new element the element has the atomic number of 113 and has an atomic mass of 281 where would you place this new element on the periodic table?
This is a homework assignment. It has been given to you to research and think out so that you will learn about and understand how the periodic table works.WikiAnswers will not do your homework for you because of this.If however there is some specific question you do not understand relating to your research about the periodic table, WikiAnswers will be happy to answer this specific question.
How can you use the Periodic Table to help you compare and contrast different elements?
you can find almost everything you need to know about any element with the periodic table. The number of electrons, average atomic mass, number of protons and neutrons. Based on it's position you can find its electron configuration. Also you can estimate the ionization energy, electronegativity, what category of elements they are. Also by looking at the cloumns of the table tells you what atoms have similar chemical characteristics. There's tons moreElement's name, symbol, atomic number, atomic mass, whether it is a metal, non-metal, metal, or a metalloid. It also can tell you the number of valence electrons, its reactivity, and can help you infer about its size. ^ I think.A. Number of electrons and protons (atomic number)B. Number of neutronsC.

You can also use this to find the number of electrons in the highest energy level of the electrically stable atom (otherwise, it would be an ion).

What two things can you learn from the atomic number of an element?
The atomic number of an element is the number of protons in the nuclei of its atoms. If the atom is neutral, it is also the number of electrons.
What can we learn about an Atom of an element if it's atomic number is known?
The number of protons in its nucleus, the number of electrons it has and its name.
What can you learn about an element by its placement on the periodic table?
you can learn if its a metal nonmetal or matalloid (aka semmimetal) you can learn the elements atomic number and you can learn what the chemical symbol is for that particular element (eg: Hydrogen would be "H" on the periodic table you will see the atomic number witch is 1 and if its a nonmetal metal or metaloid and hydrogen is a non metal hope this helps you out \m/ ([-_-]) \m/

Can it truthfully be said that whenever a nucleus emits an alpha or beta particle it necessarily becomes the nucleus of a different element?
Yes, this is essentially correct. In alpha decay, atomic number goes down by two. Beta decay comes in two types, and in beta plus decay, atomic number goes down by one, and in beta minus decay, atomic number goes up by one. In each case, nuclear transformation has occurred, and a new element appears in the place of the element that began the transformation. Use the links below to related questions to learn more.

How can you find the number of protons and electrons and neutrons in potassium?
PotassiumThe number of protons in an atom will always be the same as the atomic number, by which the periodic table is organized. So figuring out how many protons an atom has just becomes an exercise at reading the table. In this case, potassium has an atomic number of 19. If the particle is specifically an atom, then it will be neutral and the number of electrons will balance the number of protons exactly, 19 also. The number of neutrons will differ depending on the isotope - atoms of the same element with different numbers of neutrons. Potassium has three isotopes, the most common in nature being 39K with 22 neutrons.See the related question below which gives instructions on how to find the number of subatomic particles in an atom or ion based on given information.
Where can one learn about atomic time?
Wikipedia contains an article on "International Atomic Time," which provides a general discussion on the topic. For more information, see the NPL page "What is Time?"
What does the atomic number help you find out about the atom?
The Atomic Number immediately tells you the number of Protons and Electrons that are in the atom. Additionally, the At. No allows you to find it quickly on the Periodic Chart where you will learn its Symbol (a key to finding its name) and its Atomic Weight. Knowing the At. Wt. you can determine the number of Neutrons that your atom has. Etc, etc, etc,
How many protons are in helium?
There will be two protons in a helium atom. Here we have to learn an important detail regarding the atomic number. Atomic number gives the number of protons in an atom. This number primarily decides the name of the atom. Thus, if atomic number is one then it will be named as hydrogen. If the number is found to be two, then that will be named as only Helium. There by a learner must concentrate on this atomic number to know about the atom. If 82 is the atomic number then he has to identify the atom to be lead. Same manner if atomic number is 92 then that atom has to be Uranium. What will be the number allotted for, say, sodium atom? 11 is that number as there are 11 protons in it. The familiar and costly metal is gold. How many protons will be there in a gold atom? The learner must know about this detail. That number meant for gold is 79 as there are 79 protons in it. If that number is increased by one ie if it goes to 80 then that element will be identified as mercury. Hence there will be a chance to change mercury into gold by simply taking only one proton from the nucleus of mercury atom.
