The answer to the question is YES.
"Its usually 1.5 times the mean" is utter rubbish - apart from the typo. If a distribution had a mean of zero, such as the standard Normal distribution, then almost every observation would be greater than 1.5 times the mean = 0 and so almost every observation would be an outlier!
No.
There is no universally agreed definition for an outlier but one contender is values that are more than 1.5 times the interquartile range away from the median.

There would be a difference to the median. The old number wouldn't be the median but the mode wouldn't change. If the outlier is a high value, it will cause the mean value to shift to the higher side, while a low valued outlier will drop the mean value to a lower number.
it is called an outlier
In statistics, the name for that is "outlier". Another possible word is "anomaly".
A large value for the chi-squared statistic indicates that one should be suspiciuous of the null hypothesis, because the expected values and the observed values willdiffer by a large amount
In standard form, the number 12 is written as 1.2 x 10^1. This representation is achieved by moving the decimal point one place to the left and indicating the power of 10 needed to return to the original value. This format is commonly used in scientific notation to express large or small numbers more efficiently.
