Explanation:
A chemical bond which is formed in between positively charged atoms when there is sharing of free electrons in a lattice of cations is known as a metallic bond.
In a pure metal, atoms are surrounded by free moving valence electrons which move from one part of metal to another.
Thus, we can conclude that pure metals are held together by metallic bonds due to attraction between mobile valence electrons and positively charged metal ions.
2 atome nitrogen , 1 is correct
Answer:
positive charge comes from having more protons than electrons; negative charge comes from having more electrons than protons charge is quantized, meaning that charge comes in integer multiples of the elementary charge e
Explanation:
Answer : 6.41 moles of silicon are in the sample.
Solution : Given,
Moles of magnesium = 9.62 moles
The given chemical formula for talc is, 
From the given chemical formula we conclude that
The stoichiometry of magnesium and silicon is 3 : 2
3 moles of magnesium is equivalent to 2 moles of silicon
9.62 moles of magnesium will be equivalent to 
moles of silicon
Therefore, the number of silicon present in sample are 6.41 moles.
Answer:Carbonization is the conversion of organic matters like plants and dead animal remains into carbon through destructive distillation.
