Answer: H
H- C- H
H
Explanation:
Lewis structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.
Carbon is an element which belong to group 14. Atomic number of carbon is 6 that means it contains 6 electrons, Thus the electronic configuration is represented as:
. Thus the valence electrons are 4.
Hydrogen is an element which belong to group 1. Atomic number of hydrogen is 1 that means it contains 1 electron, Thus the electronic configuration is represented as:
. Thus the valence electron are 1.
The four valence electrons of carbon are shared with one valence electron of hydrogen each.
Answer:
58.44 g/mol
Explanation:
just got done with this unit two weeks ago
Amount of money that Cheryl has = $56
Cost of each notebook = $1.60
The maximum number of notebooks she can buy = n
Then
n = 56/1.6
is the inequality that shows the maximum number of notebooks she can buy with her money
On solving the inequality, we get
n = 35 notebooks.
Because there are so many different values of numbers, it would be impractical to use 1Ω, 2Ω, 3Ω... etc... Using colored bands helps make reading it a little easier to the trained eye. There are hundreds of thousands, if not tens of millions of different resistors would need to exist to cover every value. So you just use something called "preferred values" with their resistance values posted on them instead.
Explanation:
the physical and chemical properties of an element are periodic functions of their atomic number.
