Use Mendeléev’s Periodic Table to predict the formulae for the oxides of the following elements :
$K,\, C,\, Al,\, Si,\, Ba$.
Use Mendeléev’s Periodic Table to predict the formulae for the oxides of the following elements :
$K,\, C,\, Al,\, Si,\, Ba$.
$K$ is in group $1 .$ Therefore, the oxide will be $K _{2} O$
$C$ is in group $4 .$ Therefore, the oxide will be $CO _{2}$
$Al$ is in group $3 .$ Therefore, the oxide will be $Al _{2} O _{3}$.
$Si$ is in group $4 .$ Therefore, the oxide will be $SiO _{2}$
$Ba$ is in group $2 .$ Therefore, the oxide will be $BaO$.
