First you have to look at the number of protons in the element because in a neutral element or atom the number of protons and the number of electrons are the same
If the atom is an ion (i.e has a charge/valency) you either take away or add the charge to the number of electrons
for example
oxygen has 8 protons and 8 electrons
say that it has a charge of (-2)
that means that there are 2 more electrons in this particular atom because the charge is negative (electrons have negative charges) and the valency is '2'
hence add 2 electrons the the existing 8 and you have 10 electrons (HOPE THIS DOESNT CONFUSE YOU)
ll what i do is i go to answers.com and type it in hope this helped you
The number of electrons is always the same number as the protons and atomic number
The atomic number of an element is equal to the number of electrons
You Look At The Number At The Top And That Shows How Many Neutrons And Electrons They Have Alltogether.. Loll, I Think?
Actually, you take the atomic number. It's the same as the number of protons and the number of electrons.
by knowing the number of protons we can directly know the number of electrons in an element
by its atomic number. Oxygen is 8, and has 8 electrons, 2 in its first valence and 6 in its outer valence
The electrons in an atom can tell you many things about the element such as: ~the atomic number ~number of valence electrons ~what column the element is in ex: Because if fluorine is element number 9 then there are 9 electrons.
The Element Neon has 10 protons and 10 electrons.
8 electrons
43 electrons :)
4 electrons, 2 valence electrons
The electrons in an atom can tell you many things about the element such as: ~the atomic number ~number of valence electrons ~what column the element is in ex: Because if fluorine is element number 9 then there are 9 electrons.
Where do you live? Tell me how many electrons it has first. the number at the bottom of the element in bold black.
The number of electrons should balance the number of protons, which is denoted by the atomic number.
The atomic number = Number of protons = Number of electrons
How many protons/ electrons that element has and where it is on the periodic table.
simply yes
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
How many valence (outer shell) electrons an element has.
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
The Element Neon has 10 protons and 10 electrons.
8 electrons
Thorium has 90 electrons.
