How many electrons does lithium need to be unstable?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Do chemical reactions cause changes in atoms?
An atom is the smallest piece of an elemental chemical, a molecule is the smallest piece of a compound chemical (composed of several elements). However due to quantum effects, neither an atom nor a molecule has the properties that we associate with that specific chemical. You need a minimum of several hundred or thousand atoms or molecules in most cases for the "bulk" chemical properties to begin to appear.
What does the electrongavitivity of an atom indicate?
The electrongavitivity of an atom indicates an element is a part of electrons. The more electronegativity you have the more electrons you will need.
Do you need atomic number to find atomic mass?
no you do not need to know the atomic number, as that only equates to the number of protons in an atom. Most periodic charts will show you the atomic mass of an element
How many atoms are there in the chemical formula ch4?
"ch4" is not a proper chemical formula, because the atomic symbol for each element must begin (and may end) with a CAPITAL letter. The chemical formula CH4 contains 5 atoms, one of carbon and four of hydrogen.

How many atoms of an element make up sodium?
Sodium is an element- you just need one atom. Its a trick question

Why do elements have a chemical symbol?
Because to write chemical equations you need a short way of referring to an element.
If i wanted to find the chemical element of an atom what will i need?
A periodic table. Count the number of electrons neutrons and protons and the rings which contain the electrons. Then refer to the table. It's group number is the number of electrons in the outer shell. The period number is the number of shells in the atom (the rings). So one ring with one electron in it would be group one, period one. Which is the element hydrogen. 4 rings with 2 electrons in th outer ring would be calcium etc.
What is a one or two lettered representation of an element?
That is the chemical symbol of an element, such a H for hydrogen, Hg for mercury, etc.
What atoms has 39 protons?
The atomic number of an element tells us that atom's number of protons. If the atom is neutral, its number of protons is going to equal its number of electrons. Thus, we need only find the element with the atomic number of 39, which is yttrium.
What is the chemical combination of symbols that represents a compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound. For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
What elements need to be present for a compound to be considered organic?
The indispensable chemical element is carbon.
