Answer:
5.47 B.M
Explanation:
✓We were given electronic configuration of argon as [Ar] 3d5.
✓This is a divalent ion. It has atomic number of 25.
✓magnetic moment can be calculated using below expresion
√[n(n+2)] .....................eqn(1)
✓ It has 5 unpaired electrons. Then n= 5
✓ [n(n+2)]
✓ substitute the ( n= 5) into eqn(1)
Then magnetic moment= [n(n+2)]
= [ 5(5+2) ]
= 5.47BM
Answer:
When water moves through the water cycle, it changes between these states of matter over and over again. The water cycle is the process that moves water between the air and Earth's surface. ... With enough energy, the molecules of liquid water change into water vapor and move into the air. Think of the many ways that the hydrosphere and the atmosphere connect. ... The geosphere, in turn, reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere. It receives water from the hydrosphere and a living medium from the geosphere.
Electrons: negative
Protons: positive
Neutrons: nuetral
An example would be iodine has a lower relative atomic mass than tellurium, so it should come before tellurium in Mendeleev's table. In order to get iodine in the same group as the other elements with similar properties such as fluorine, chlorine, and bromine, he had to put it after tellurium, which broke his own rules.
It is a <u><em>chemical compound</em></u> formed with a metal (mainly positive cations) with oxygen.
It is formed through the air as they react in the air together.
They are also BASES - ALKALINE (so neutralise acids)
