Tell how many significant figures this number contains. 0.6

1 significant figure is the Answer

Explanation:

The zeros are not trailing after the digit 6. Hence they are not significant.

Rules:  

Non zero digits are always significant.

For example 2356 has 4 significant figures

Zeros between Non zero digits are always significant.

3007 has 4 significant figures

In a decimal trailing zeros are significant.

For example 0.0003 has 1 significant figures and 0.003000 has 4 significant figures.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

answer; 4 electrons;
