Answer:
a chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.
Explanation:
the self-sustaining fission reaction spread by neutrons which occurs in nuclear reactors and bombs.
a series of events, each caused by the previous one.
Answer:
p - subshell contains three orbitals 2px, 2py and 2pz.
Explanation:
Each p - subshell consists of two section better known as lobes which lie on either side of the plane passing through the nucleus. The three p-orbitals differ in the way the lobes are oriented whereas they are identical in terms of size, shape and energy. As the lobes lie along one of the x, y and z axis, these three orbitals are given the designations 2px, 2py and 2pz. Thus, we can say that there are three p - subshells whose axes are mutually perpendicular.
Pure substance- a material that has constant composition. It has distinct chemical properties.
Element- a substance that cannot be broken down into any other substances.
Compound- substance made up of two or more different elements.
Answer: 35.4 degrees
Explanation: because it cold
In the periodic table, there is a size trend.
The trend occurs horizontally and vertically on the table.
- From right to left, the atomic radius gets larger.
- From top to bottom, the atomic radius gets larger.
The reasoning for this is the additional energy levels and electrons being added as you go from right to left or top to bottom.
We can see that Magnesium is higher and more right in the periodic table than sodium and calcium.
Thus, Magnesium has a smaller atomic radius than both sodium and calcium
