First you start of by finding out what the atomic number is of the element, in this case the number is 17.
You then draw a circle, you are aloud to put 2 electrons on this circle. you then draw another cirlce around it, you are aloud to have 8 electrons on the outer shells. you will ned a third circle to put the rest of the elcetrons on to it.
in total you should have the smallest circle with 2 electrons, the middle circle with 8 and then the outer shell with 7 elecrons on it. you can draw the electrons as dots or crosses on the cirlce line.
because the outer shell is not full and only has 7 electrons instead of 8, this means it will be reactive. if an element has a full outer shell then it becomes unreactive.
hope that helped. :)
So that it can be identified by an enlarged picture
"Candium" is an imaginary element often used by chemistry classes to help students better understand the concept of atoms. Candy is used to represent electrons, neutrons, protons etc. depending on the specific lab given.
atoms
A handshake can be used to represent trust or an object portraying a handshake. Perhaps a heart can also represent trust.
The earliest fossils represent plants.
dinosaurs
to what number the element can count to
both are pure substances, but atoms represent the smallest bits of elements. compounds are chemically combined atoms, molecules represent the smallest bits of compounds. atoms cannot be broken down into simpler substances, compounds can be broken down into atoms.
Protons, nuetrons, and electrons
With a line
4 atoms of helium.
atomic number
Atoms are too small to see.
This is the picture.
6.3x10^24 aluminum atoms represent 1 mole of aluminum atoms because Avogadro's number is approximately 6.022x10^23.
Different atomic numbers represent different elements.
