Exploring Ion Formation and Binary Ionic Compounds

What does the term 'binary' in binary ionic compounds refer to?

• The presence of two different elements

• The presence of two non-metals

• The presence of two metals

• The presence of two ions

What is the main difference between Type 1 and Type 2 binary ionic compounds?

• Type 1 is formed from two metals, Type 2 is formed from two non-metals

• Type 1 has a non-metal anion, Type 2 has a metal anion

• Type 1 has a metal cation with a fixed charge, Type 2 has a variable charge

• Type 1 compounds are always solid, Type 2 compounds are always liquid

How can you remember that cations are positively charged?

• Cations gain electrons

• The word 'cation' has a 't' in it, resembling a plus sign

• Cations are always metals

• Cations are larger than anions

What happens to a sodium atom when it loses one valence electron?

• It becomes a neutral sodium atom

• It becomes a sodium ion with a +2 charge

• It becomes a sodium ion with a +1 charge

• It becomes a sodium ion with a -1 charge

What is the charge of a chloride ion after gaining one electron?

• -1

• +1

• -2

• +2

What is the process for forming a cation from a metal atom?

• Gaining electrons to achieve the electron configuration of the nearest noble gas

• Sharing electrons with another atom

• Neither gaining nor losing electrons

• Losing electrons to achieve the electron configuration of the nearest noble gas

Which group of elements typically forms a +1 charge when forming an ion?

• Group 1A

• Group 2A

• Group 3A

• Group 4A

What charge does nitrogen typically have when it forms an ion?

• -2

• +3

• -3

• +2

How do you name a cation?

• The name of the cation is the element's name with 'ite' at the end

• The name of the cation is the element's name with 'ate' at the end

• The name of the cation is the element's name with 'ide' at the end

• The name of the cation is the same as the name of the element

How do you name an anion?

• Add 'ate' to the element's name

• Add 'ite' to the element's name

• Take the element's root name, cut off the last syllable, and add 'ide'

• Use the element's full name
