Is Rutherford’s model correct?

‘ It was eventually discovered that this model does not accurately represent the behavior of electrons or the sizes of particles. The Rutherford model is one of the most popular models of the atom even though it was only considered accurate from 1909 to 1913.

How accurate is Bohr’s model?

2 Answers. The main problem with Bohr’s model is that it works very well for atoms with only one electron, like H or He+, but not at all for multi-electron atoms. The application of Schrodinger’s equation to atoms is able to explain the nature of electrons in atoms more accurately.

Is the atomic model wrong?

We know that Rutherford’s Atomic Model was an important step forward in the study of atomic physics, but it is wrong because it does not obey conservation of energy. And therefore Rutherford’s Atomic Model doesn’t make sense in terms of conservation of energy and that was why later on scientist got new atomic models.

What is the lowest possible energy level?

ground state

What is the highest energy level to have electrons in Mg?


What is the ground state electron configuration for mg2+?

The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.

How many energy levels are there in MG?

Number of Energy Levels: 3
First Energy Level: 2
Second Energy Level: 8
Third Energy Level: 2

How many stable electrons does magnesium have?

two electrons
