This is the inert or noble gas argon. We find that argon (Ar) has an atomic number of 18, and its electron count per shell is 2, 8 and 8. A link can be found below.
Potassium has 19 electrons.
SDGH
Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
a nucleus with 11 p, 12n with 3 shells. the 1st shell has 2e's, the 2nd has 8e's, and the 3rd has only 1e
Chlorine has 17+ Prontons & 17- Electrons Energy levels go 2e - 8e - 18e - 32e So Chlorine has 2 in the first shell which leaves 15 (17e-2e = 15) So that means 8 in the second shell which leaves 7 (15e-8e = 7) That leaves 7 in the third shell The answer is 8 Anything with 10 or more electrons or an atomic # 10 or more would have 8 for the second shell.
Group #15 has 5 valence electrons
An ionic bond takes place when one atom gives up an electron to another atom in order to have a stable valence. Whereas covalent bonds share electrons to sustain a stable valence. The Bohr diagram for Bismuth would be: Bi)2e-)8e-)18e-)32e-)18e-)5e- & Fluorine would be: F)2e-)7e- The valence for Bismuth has 5 electrons and Fluorine has 7 electrons, hence Bismuth requires 3 more electrons and Fluorine needs 1 more electron to become an octet. Therefore, to balance BiF3: for one Bismuth atom you will need 3 Fluorine atoms attached, both atoms will share the electrons to satisfy a complete octet in the valence for both atoms.

the electron dot structure for lithium is Li ' (the element symbol with one dot on the upper right side)
2e+0 x 2e+0 x 2e+0 = 8e+0
that's easy. 32 neutrons means that the mass of protons is 25 (as is the electrons) so all i have to do is look for the right one. simlpy thinking there are 2e (2 electrons on te inner shell) ten each one afterwards has up 8e unless there are no more electrons to fill the shell. in this case its like this: 2e, 8e, 8e, 7e. the element is infact manganese in group 5 (Mn). magnese will react with anything from group one easily at a 1:1 basis and will react with anything from group 2 at a 2:1 basis (the 2 representing magnese).
Bohr's model explain the structure of mono electronic system
a nucleus with 11 p, 12n with 3 shells. the 1st shell has 2e's, the 2nd has 8e's, and the 3rd has only 1e

Group #15 has 5 valence electrons
3c x 8e = 24
12de2 and 8e Looks like 4e is common to both.
