The oxidation state of an atom is the fictitious charge that an atom would have if all bonds between atoms of different elements were 100% ionic. Thus, oxidation is better defined as an increase in oxidation state, and reduction as a decrease in oxidation state.
Most babies take their first steps sometime between 9 and 12 months and are walking well by the time they're 14 or 15 months old. Don't worry if your child takes a little longer, though. Some perfectly normal children don't walk until they're 16 or 17 months old.
Most babies take their first steps around their first birthday, but the age range varies from 9 to 18 months. Don't worry if your baby takes a few detours along the way. Some kids never crawlâthey go straight from standing to walkingâand that's perfectly normal. What's important at this stage is that your child is using arms and legs together to become mobile. If your child is doing any of the following, walking is not far behind: 1  Rolling around. 2  Crab walking. 3  Scooting. 4  Climbing stairs using his hands.
