QuestionName the compound and find the charge of Li and O ions. Spelling matters.
Studdy Solution
STEP 1
Assumptions1. The compound is .
. The compound isionic, meaning it is formed by the transfer of electrons from one atom to another.
3. The charge on an ion is determined by the number of electrons it has gained or lost.
STEP 2
First, we need to name the compound. In anionic compound, the metal (in this case, Lithium) is named first, followed by the nonmetal (in this case, Oxygen), which has its ending changed to -ide.
STEP 3
To determine the charge on each ion, we need to know the number of valence electrons for each element. Lithium, as a member of Group1 on the periodic table, has1 valence electron. Oxygen, as a member of Group16, has6 valence electrons.
STEP 4
In anionic compound, atoms gain or lose electrons to achieve a full outer electron shell, typically of8 electrons (octet rule). Lithium, with1 valence electron, will lose this electron to have a full outer shell. Therefore, the Lithium ion has a charge of +1.
STEP 5
xygen, with valence electrons, will gain2 electrons to have a full outer shell. Therefore, the Oxygen ion has a charge of -2.
The compound is named Lithium Oxide. The Lithium ion has a charge of +1 and the Oxygen ion has a charge of -2.
