Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
How can you calculate the number of electrons in an atom?
For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the periodic table of elements.
What do quantum numbers of electrons represent?
The energy levels and orbitals the electrons are in
Do the groups in the periodic table go down or across?
The groups in the periodic table of elements (the "normal" one) go down the chart. That's because we arranged the elements in increasing order of atomic number, but also in order of valence electron count. It is by looking at the position of an element on the periodic table that we can determine the number of electrons in its outer or valence shell, and we can, thereby, make some good guesses about its chemical properties. As a quick "for instance" here, look at the elements going down the left hand side of the table. These are the Group 1 elements, which are hydrogen, lithium, sodium and on down. And all of them have one lonely electron in their valence band. If you guessed that these elements are reactive and are looking to "hook up" with elements that want to borrow electrons, you'd be right. Further, if you consider the elements that lack only one electron in their valence band from having a full outer shell, which are the Group 17 elements beginning with fluorine, chlorine and the rest of the so-called halogens, you'd guess that these elements are also highly reactive and want to borrow an electron real bad. The last piece of the puzzle is that if you put one atom of a Group 1 element with 1 atom of a Group 17 element, you will get a chemical reaction where the Group 1 element gives up its valence electron to the Group 17 element because that element steals it. The elements form a chemical compound with an ionic bond, and they do so in a one-to-one ratio in every case. That's the whole idea behind the construction of the periodic table of elements. It lets us guess with just a glance what kind of things we can expect of the elements we inspect as regards their chemistry - how they react with other elements. Simple and easy for us, but the table and its construction represent the "coming together" of the life's work of a number of bright and creative scientists. Why not honor them and learn a few things about this handy, clever construct and what it can do for you? If you need a link to a good periodic table, use the one below. It will take you to the Wikipedia periodic table, and what's cool is that each element is a hyperlink to the Wikipedia post on that particular element. What a clever idea.
Which of these atoms has the greatest number of electrons?
Among the elements that occur in nature, it's Uranium, with 92 protons in the nucleus. Small amounts of atoms with higher atomic numbers are produced in particle accelerators. Their nuclei are unstable, and break down into nuclei with lower atomic numbers.
Why do elements within a periodic the periodic table have different properties?
They have different numbers of valance electrons...
Why do elements within a period of the periodic table have different properties?
They have different numbers of valance electrons...
How are the element within a row different?
They have different numbers of valence electrons.
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
What is a family on the periodic table?
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
Do Atoms have no overall eletric charge?
Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
Are the numbers of neutrons the same for elements in the same column on the periodic table?
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
What is the law called that states the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements?
An element's atomic number is equal to the amount of electrons or protons in an atom of that element. When an atomic number increases or decreases, the amount of electrons is changing.
What do elements within a group have a similar number of?
Chemical elements that are in the same group within the periodic table have the same numbers of electrons in the outermost shell. This gives them similar reactivity.
What is the relationship between column numbers and number of valence electrons?
theses are not called colmns but are called groups of periodic table.the relation between them is that in the periodic table the elements are placed in such a way that the the number of electrons in the outermost shell are equal to the group number.
How do you find electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
What does a periodic table have?
a modern periodic table should have the 118 elements, their atomic numbers, and their masses. to find the number of protons and electrons, they are the same as the atomic number. to find the neutrons, subtract the protons from the mass.
