How atoms in a group are similar?
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
What does the group tell us about the structure of the atom?
Atoms in the same group have similar structures.
What does subscript tell you in an ionic compound?
look crazys all you have to do is go look it up b/c this is not going to get you the answers lazy people u need to work for it now look it up on google not answers .com lamo
What do oxidation numbers tell us?
The oxidation number now tells you how many more or less electrons the atom has.
How many electrons are present in 4g methane?
Let us get number atoms of the constituent first.4 grams CH4 (1 mole CH4/16.042 grams)(6.022 X 1023/1 mole CH4)= 1.5 X 1023 atoms of methane========================so,Carbon is one to one in the molecular formula, so let's get the number of hydrogen atoms in this mass methane.1.5 X 1023 atoms CH4 (4 mole H/1 mole CH4)= 6 X 1023 atoms hydrogen======================now, we proceed to find electrons1.5 X 1023 atoms carbon * 6 electrons= 9 X 1023 electrons carbon--------------------------------------6 X 1023 atoms hydrogen * 1 electron= 6 X 1023 electrons hydrogen--------------------------------------------added together= 1.5 X 1024 electrons in 4 grams methane-------------------------------------------------------------( call it 2 X 1024 electrons methane to be in line with significant figures )

What does the name diphosphorus pentoxide tell us?
Tells us there are 2 phosphorus atoms and 5 oxygen atoms
What does the group number of A tell us about the valence electrons?
no
Why do atoms give us electricity?
Electrons can be made to move from one atom to another. When those electrons move between the atoms, a current of electricity is created. The electrons move from one atom to another in a "flow." One electron is attached and another electron is lost.
What does the number of electrons on the outershell of an atom tell us?
The valence of the element
How can you find group no?
The number of valence electrons tell us the group number of that element.
What does the group tell us about the structure of the atom?
Atoms in the same group have similar structures.
What does temperature tell us about atoms?
Temperature is related to the average energy per particle.
What things are made up of atoms?
Everything! Atoms are in the air, water, and even us ! Atoms are are the elementary chemically indestructible components of any material in the world. Atoms are the bricks of molecules.

What do electrons have to do with chemical bonds?
Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
How does the conservation of matter tell us about atoms in chemical reactions?
Matter is neither created nor destroyed. Only change of bonds occur in atoms.
