i need help to solve this

Classify each statement as applying to ionic bonds, covalent bonds, or both types of bonds.

oppositely charged ions are attracted to each other

form after one atom donates an electron to another atom

polar water molecules can pull them apart

form when atoms share electrons

stay together in water

found in biomolecules, such as proteins and DNA, that make up cells

a strong interaction between atoms

attraction based on the number of electrons in the outermost shells of the elements involved

Hi Nahida S., Is your question about how to apply a Venn diagram, or in how to sort though the descriptions for which types of bonds they apply to? If the former, just set the light blue section on the left as "true of ionic bonds only", the center biconvex lens shape as "true of both types of bonds", and the right-hand section as "true of covalent bonds only". (There are also hydrogen bonds, dipole-dipole attractions, dipole-induced_dipole attractions, dispersion forces, and metallic bonds, but don't fret about those yet, obviously). These are all fairly clearcut descriptions, except perhaps the last one (since the number of electrons in a particular shell completely determines an element's chemistry possibilities!); you should be able to take your idea of an ionic lattice (NaCl, perhaps) and a covalent molecule (glucose, perhaps) and "try them on for size" against the descriptions. If not, respond and I'll help you further. --Cheers, -- Mr. d.

i just need to solve by how to sort though the descriptions for which types of bonds they apply to. because i am confuse to the one " a strong interaction between atoms". i was trying to put this one on a last circle but it keeps saying no

Ionic:

form after one atom donates an electron to another atom

polar water molecules can pull them apart


Covalent:

form when atoms share electrons

stay together in water

a strong interaction between atoms


Both:

found in biomolecules, such as proteins and DNA that make up cells

attraction based on the number of electrons in the outermost shells of the elements involved
