Answer:
There stable oxidation state is +3.
And they have only three energy levels
1: An atom is nuclear energy that is extremely small. It is the smallest unit of matter that forms a chemical element. It is the building block for all matter in the universe. They are made up of even smaller particles. Particles that make up an atom are electrons, neutrons, and protons.
2. What’s different inside of an atom to make them into different elements is that the number of protons in an atom is the defining feature of an atom. This is what makes a element different from another.
Hope this helps!!
The Molarity of a solution = number of moles / volume.
Volume = 244ml = 0.244L
So it follows that number of moles = Molarity * volume
Number of moles = 0.135 * 0.244 = 0.03945.
Hence the number of moles = 0.03945
Answer:
it is calcium and bromine
Explanation:
this is because they are both ionic compounds
The Outer space of the colder region has the temperature of 2 Kelvin.
<u>Explanation:</u>
Even the sun is in extreme hot condition or temperature, but the outer space or called as space is extremely cold that is around 2 Kelvin.
In the space there are no objects or nothing to make the heat to travel through, even though the sun's heat travels in space there will be nothing like molecules or atoms are there to transfer or absorb it. So, at the outer regions of colder space the temperature is only 2 Kelvin.
