There are 4 electron pairs (3 bonding and 1 lone pair) so the angle is 107 degrees. The 4 electron pairs are repelled to give a tetrahedral arrangement but the molecule has a pyrimidal shape due to the lone pair.
Answer:
né si è fatto che non mi hai detto niente
Explanation:

A molecule is usually reserved to represent the smallest particle of a compound.
There are four sodium atoms in the product.
A reaction equation is said to be balanced when the number of atoms of reactants are equal to the number of atoms of products according to the balanced reaction equation.
Given the reaction between sodium metal and oxygen, the reaction could be written as; 2Na(s) + O2(g) ----> 2Na2O(s). We can see that there are four sodium atoms in the product.
