Answer: a ) NaCl
b) No compound.
Explanation:
Atomic number of A is 11 , thus it is sodium. It has electronic configuration of 2,8,1 and thus has 1 valence electron and can form .
Atomic number of B is 18 , thus it is argon. It has electronic configuration of 2,8,8 and thus it is an inert gas.
Atomic number of C is 1 , thus it is hydrogen. It has electronic configuration of 1. It can only share electrons.
Atomic number of D is 17 , thus it is chlorine. It has electronic configuration of 2,8,7 and thus has 7 valence electron and can form .
a) A and D :
Here Sodium is having an oxidation state of +1 called as cation and anion is . Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
b) B and C
As B is an inert gas , it wont combine with C.
Answer:
Neon
Explanation:
Neon is a monatomic gas. With a complete octet of outer electrons it is highly resistant to removal of any electron, and it cannot accept an electron from anything.
Volume of a cube is length times width times height so do 125 times 37 times 68
Where's the list? If you show it maybe I can help
