Each one of the elements in group 13 has three electrons in the outer shell of their nuclear structure
Answer and Explanation:
Most of the distances in the galaxy are measured in light years instead of meter because the distances in galaxy are very large and it is very difficult to measure in meters and light year is the largest unit of distance so it is very easy to measure large distances in light year so we prefer light year instead of meters for measuring distances in galaxy.
<u>Answer:</u> The word for the definition of an electron in the highest occupied energy level of an atom is " valence electron".
<u>Explanation:</u>
A valence electron is an external shell electron associated with an atom in chemistry and physics that can participate in the creation of a chemical bond if the highest occupied energy level of an atom is not closed. All atoms in a single covalent bond add one valence electron to form a mutual pair.
The periodic table showcases the arrangement of valence electrons group and block wise like:
- Alkali metals have <em>n </em><em>s</em> 1 as external shell configuration like H, Li, Na, K etc.
- Alkaline metals have <em>n</em> s 2 as external hell configuration like Be, Mg, Ca etc.
- p-block comprises group 13 to 18 having general electronic configuration <em>n </em><em>s</em> 2, <em>n</em><em> p</em><em> </em>1–6.
- d-block or transition metals have general electronic configuration (<em>n</em>-1) d 1–10, <em>n </em>s 1–2.
- f-block or inner transition metals have general electronic configuration (<em>n</em>-2) f^1–14 (<em>n</em>-1) d^0-1 <em>n </em>s^2.
You probably do this as a DC circuit which is not quite correct, but it will get you an answer. The study is a great deal more complicated.
Problem One: Secondary Power.
W = E * I
E = 10 A
I = 24V
W = 24 * 10
W = 240 Watts.
Here's the thing you have to know. These transformers are 100% efficient (or are assumed so). So whatever wattage is in the secondary, it is the same as that in the primary.
Primary Power = Secondary Power
Secondary Power = 240 Watts
Primary Power = 240 Watts
W = E * I
E = 240 volts
W = 240 watts
I = W/E = 240 / 240
I = 1 Amp. Answer Part One
Part Two
Answered above. 240 watts.
Part Three
Answered above. 240 watts.
Secondar
The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time.
Take that as you will
