∙ 7y agoNo, a leading zero is NEVER a significant digit.

That is correct.
if between two other digits ex: 3009 or ending zeros when there is a decimal ex: 54.300
Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits. Zeros are sometimes significant and sometimes aren't: # Zeroes placed before other digits are not significant; 0.0968 has three significant digits. # Zeroes placed between other digits are always significant; 70063 kg has five significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 * 103 has four significant digits 8.20 * 103 has three significant digits 8.2 * 103 has two significant digits
There is nothing that zeros are always considered. Zeros in some positions are significant, in other position are not. There is no always.
When they are between two non-zero digits or if there are after the decimal point. For example, the 0 is not significant in 1340 but it is significant in 1304 or 1340.0
No. 0.0000123 has three significant digits.
No, they are not.
True

All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
Five. Zeros that are after the decimal and are after nonzero integers are always significant.
There is nothing that zeros are always considered. Zeros in some positions are significant, in other position are not. There is no always.

There are 3 significant digits in 4.00 and 2 significant digits in 7.0. Zeros between non-zero digits or at the end of a number after a decimal point are considered significant.
All the digits are significant in this case. A zero between other digits is always significant, and all zeros after the decimal point are significant.
