Answer: 4

Explanation:

To find the significant digits we have few methods.

METHOD 1--Count from left to right

A number that has a decimal point, count digits from the first number from the left that isn't zero.

METHOD 2--Count from right to left

A number that doesn't have a decimal point, count digits from the first number from the right that isn't zero.

-----------------------

It is obvious that 507.2 has a decimal point, so we count from left which we will start with 5.

5, 0, 7, 2

There are 4 digits.

Hope this helps!! :)

Please let me know if you have any question or need any further explanation

Finger [1]
<span>Paramagnetic, an easy way to check is to see if it is the last element within the orbital and you can do that simply by looking at the periodic table. The s orbital has two, the p has 6 so on and so forth. Some elements are considered diamagnetic if they are almost completely full. </span>
