Multiple Choice

When do we use roman numerals in naming ionic compounds?

• only when compounds are common

• when the nonmetals are with subscript

• depends if the cations have varying charges

• it is used for all transition elements

Multiple Choice

Which of the following is an example of binary ionic compound?

Multiple Choice

How do we predict the chemical formula of ionic compounds?

• we just write the symbols and name them

• we criss-cross the charges and write it as subscript

• we place the charges as its subscript

• we jumble the charges and guess what will be the resulting compounds

Multiple Choice

How do we draw the LEDS of an ionic compound?

• we look for the charges and crisscross

• we look for the valence electrons of each element in writing the dots beside the element

• we just transfer electrons by placing a line

• we allows the nonmetals to do the sharing
