What differientiates metallic and non-metallic elements on the periodic table at a subatomic level?
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
What is the difference between an ion and an isotope?
an ion has a different number of electrons and an isotope has a different number of neutrons then listed on the Periodic Table or your sample
Does the atomic number equal to the number of electrons in an atom?
yes it does Update - Correct, the atomic number which sorts each element on to the periodic table is the amount of electrons inside an atom of that element. If an electron is lost then it becomes a positive ion but if an electron is gained the atom becomes a negative ion.
Do all atoms in the periodic table have the same number of electrons?
Not all atoms on the periodic table have the same number of electrons. It's atomic number is the number of protons and electrons, and since all the elements have different atomic numbers, they all have different numbers of electrons.
What element is on the 4th period on the periodic table that has 29 electrons?
The number of electrons is not the key factor in determining an element, because ions can have more or fewer electrons. However, assuming an element that hasn't gained or lost any electrons, the element would be Copper.

What is a cation and were can you find it in the periodic table of elements?
The periodic table contain neutral atoms not a list of cations; most metals are to right.A cation is an atom who lost electrons.

Does group 2 on the periodic table gain or lose electrons?
they will lose electron to form mono positive cation
How many electrons are gained or lost when selenium forms an ion?
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
How many electrons orbit nitrogen's nucleaus?
It depends on the atomic number. For example, to find the number of electrons in carbon, look at a periodic table. You will see that the atomic number for carbon is 6, so 6 electrons orbit a carbon atom'snucleus.
Charges of all elements?
Elements are neutral as their number of electrons equals the number of protons. If an atom has lost one of it's electrons it becomes a positively charged ion or an cation, if it gains an electron it's a negatively charged ion or an anion. Generally if an atom is on the right hand side of the periodic table it gains electrons to become negatively charged and fulfil it's valiance shell. If it's on the left hand side of the periodic table it tends to loose electrons and become positively charged. The amount of charge on each ion depends on the what the atoms are bonded to. Example, NaCl (Table Salt) is actually Na+ Cl-
What is the charge on lead with 78 electrons?
+4 On the periodic table, all elements are neutral. And that is the key to this problem. Lead (Pb) on the periodic table has an atomic number of 82. Therefore it has 82 protons. How many electrons would it need to be a neutral atom then? Obviously, 82! So if we have 82 electors and 82 protons we have neutral lead, but we don't have 82 electrons we only have 78. Therefore neutral lead lost negatively charged electrons. When you lose a negative you become more positive. So we have a charge of +4, since 82-78=4. In general the solution to this problem is: (Atomic Number) - (Number of Electrons) = (Net Charge)
How many electron are gained or lost by an atom?
Depends on their place on the Periodic Table.
