Chemistry Help

I need to know two things

1) What is a Penza Table?
2) How do you count atoms, you know the one with that has the subscripts and stuff.

I'm not sure about a Penza Table, but to count atoms with subscripts i easy. Say you have C with a subscript of 2. All that means is two Carbon atoms in the forumula. If you have Mg with 10, then that's ten Magnesium atoms in the forumula.

if you really want to get into the atom thing then you use this table: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s. s- sublevel holds 2 electrons (1 orbit), p- sublevel holds 6 electrons (3 orbits), d- sublevel holds 10 electrons (5 orbits), f- sublevel holds 14 (7 orbits). if u need any explaination of what i just said im me.

There is no such thing as a "Penza Table" in Chemistry. The closest thing is a Penza Table lamp.

Are you shure you dont mean a Pariodic Table?

If so, it lists all the elements, with their names, symbols, atomic number, and relative atomic mass.

Look i came first in my year and ill help as much as i can k

Well first I never heard of a panza table (sounds like a tank table)

Figuring out how many electrons is in tht atom in the cloud is the first matter of order. First you must know that the 1st electron cloud contains 2 electrons then the 2nd has 8 the same as 3rd (and im guessing your not going past the 3rd) then you should be able to figure it out from there. eg:Hydrogen (H) has 1 electron cloud and 1 electron in tht cloud and the rest really explains itself.

Also just remeber tht the atomic No. is the amount of proton in tht atom
Hope tht helps.
