Answer:
7.34684 × 10^23 atoms
Explanation:
Well, one mole is basically
6.022 × 10^23 atoms. So 1.22 moles would be
6.022 × 10^23 ⋅ 1.22 atoms.
6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms
The p block represents the non-metals while the s and d blocks represent the metals. Non-metals (p block) usually have 4 or more valance electrons that they want to give away, and for this reason they tend to form negative ions. Non-metals are dull, are poor conductors of heat and electricity, have low density, and have low melting and boiling points. On the other hand, the metals (s and d block) usually have 3 or fewer valance electrons and tend to form positive ions. They are shiny, are good conductors of heat and electricity, have a high density, and have high melting and boiling points.
Answer:In 1752
Explanation:Benjamin franklin in 1752 to prove that lightning was electrical,he flew a kite during a thundorstorm.He tied a metal key onto the string and as he suspected it would ,electrically from the storms clouds flowed down the string ,which was wet and he received an electrical shock.
