Answer:
For the HCCH Lewis structure you'll need to form a triple bond between the two carbon atoms. Hydrogen atoms only need two electrons for a full outer shell. There are a total of 10 valence electrons for the HCCH Lewis structure.
The atomic number of an element tells you how many protons each atom has. Losing an electron won't affect the number of protons. It will, however, change the charge on the atom. Protons are positive and electrons are negative. If there's more positive than negative then the atom has a positive charge. So the charge for the sodium atom would be +1
Answer
A runner ran 20 miles in 150 minutes. If she runs at that ... run in 15 minutes? How fast is she running in miles per hour? What is her pace in minutes per mile?
Explanation:
In Chemistry, a reactivity series of metals , also known as the activity series refers to the arrangement of metals in the descending order based upon their reactivity .
<u>Salient Features</u> :-
- The metal at the top of the reactivity series are powerful reducing agents since they are easily oxidized.
- The reducing ability of metals grows weaker while traversing down the series.
- The electro-positivity of metals also reduces while moving down the reactivity series.
- Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower in the series.
<u>The metal reactivity series is given below</u> :-
To access the reactivity of metal , from the given reactivity series identify any of the metal and locate the reactivity based upon the choice of reactivity. The metal at the top (Potassium) is most reactive and the metal at the bottom (Platinum) is the least reactive.
