a) Number of protons = number of electron in the atom = atomic number
So it has 7 protons answer

The wind vane, the rain gauge, the anemometer, the barometer, and the thermometer.
Answer:
[MA4B2]2+
Explanation:
Octahedral species are species that has a coordination number of of six. This means that six ligands are attached to the central metal atom/ion.
For any octahedral specie to exhibit geometrical or cis-trans isomerism, it must have the formula EX2Y4 as in [MA4B2]2+, hence the answer above.
