Answer:
the amount of valence electron, cna be found in the periodic table, which is called the atomic number which is top of the symbol
hope this helps!!! best fo luck to you
Explanation:
The boiling point of liquid nitrogen, liquid argon, and liquid oxygen are -196°C, -186°C, and -183°C respectively. So, the correct order is nitrogen, argon, oxygen.
<u><em>Answer</em></u>
<u><em>Explanation</em></u>
- In periodic table, the elements have almost same properties are present in the same group. As Mg and Sr are present in group II-A, so both behave most likely to each other due to having same valence shell electrons as well.
- Si and Sn are present in group IV-A which have same behavior but different one from Mg due to different groups.
- S is present in group VI-A which show different properties from all others one especially from Mg.
i think helium hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
B) Cu(OH) 2 Is the resulting answer when H20 is decomposed.
