Here is an explanation:
the correct answer is C
when a metal and a non Metal react the bond form is always ionic
from the question Y20 is a metal while z8 is a non metal when writing the formula for the reaction the metal is written first followed by the non metal.
that's why we the compound to be YZ

Here is an explanation:
the answer shud b C based on logistics except if myschool.com thinks anoda name for electrovalent is covalent den dey re right...ionic/electrovalent

Haas's, myschool.com.ng the answer is c Na, please correct this.
We're getting of wrong answers

The selected answer is wrong
Y has 2 valence electrons
Z has 6 valence electrons
hence for them to maintain a stable octet Y has to give out its electrons(Electrovalent/Ionic bond)

The selected answer is wrong:
ionic bond gives out electron not sharing of electron just like covalent so element y with atomic number of 2 which is 2 8 8 2 is to give out two electron to reach a stable configuration while element z need two electron to atain a stable configuration

The correct option is option C. Y=Calcium nd Z=Oxygen nd calcium bonds with oxygen ionically to form Calcium oxide which is CaO(YZ). So Option C is d correct option. Please correct it quickly @ Myschool
