What are elements composed of?
Elements are composed of atoms, which are made up of: protons,neutrons, and electrons. The number of protons in one atom of an element is equal to the periodic number of the element. If the element is in it's standard state(has no charge), then the number of electrons are equal to the number of protons. the number of neutrons can be determined by taking the atomic mass and subtracting the number of protons.For example 1 K (Potassium) atom has:19 Protons20 Neutrons19 Electrons
How many atoms of each type are in C17H19NO3?
There are four elements, vix. Carbon,(C) , Hydrogen(H), Nitrogen (N) and Oxygren (O). There eight(8) x carbon nine (9) by hydrogen one (1) by nitrogen two (2) by oxygen . Total number of atoms is 8+9+1+2 = 20 The answer!!!!
What is the mass of 19 atoms of copper in grams?
Not much! 19 atoms Cu (1 mole Cu/6.022 X 1023)(63.55 grams/1 mole Cu) = 2.0 X 10-21 grams of copper ---------------------------------------

How many different kinds of elements are there?
I think 98. Scientists believe there are 109 different kinds of elements.Nintey of these elements have been made by nature. They can be found in the earth's crust and atmosphere. The other 19 elements have been made in science laboratories. Scientists are still looking for more elements. They are still trying to make more of them in their labs as well. Now this is not the worng answer i got it from a text book. that was at my school. THMS all the way......
How do you get the electron configuration of potassium?
The atomic number of potassium is 19. This means that potassium atoms have 19 protons in their nuclei. Neutral potassium atoms will also have 19 electrons. So then you follow the rules for the orbital filling pattern for the atoms of the elements, until you get to 19 electrons, and you get the following: 1s22s22p63s23p64s1.
What elements have 10 neutrons in their neuclius?

What is the average size of atoms in terametres?
Using that unit of measure, about 1 to 2 x 10e-19 terametres. It's probably a good idea to use a smaller unit of measure than terametres to measure atoms.
