6.941 tells you the nucleon number (total number of protons and neutrons in the nucleus of an atom)
3 tells you the proton number( number of protons in the nucleus of an atom.)
When drawing this you must know the number of protons , electrons, and neutrons of that element. Well in this question, everything’s been given. No. of protons = 3
No. Of electrons = 3 *REMEMBER, NUMBER OF PROTONS AND ELECTRONS ARE EQUAL WHEN THE ELEMENT IS IN ITS ATOMIC FORM.
No. Of neutrons= 4 neutrons. When rounding 6.941, it is 7. Then simply subtract 7-3 to get 4.
Now time to draw this. First you must know the number of electron shells does lithium has. Since lithium is in period 2, it has 2 electron shells.
Then, you must know what is the valence electron of Li. It is 1, since it is a group I element/alkali metal.
Also remember the structure. Electron are surrounding the nucleus of the atom on electron shells while the nucleus is in the center of the atom. Nucleus contains the protons and neutrons. REMEMBER THE FIRST SHELL SHOULD CONTAIN ONLY 2 ELECTRONS WHILE THE SECOND SHELL WITH 8 ELECTRONS AND GO ON.
Hope this helps and if I’m correct can you add me to the brainliest?
