There are four layers of these electrons are, s, p, d, and f.
Each one has a certain number of shells, in different shapes, that can hold two electrons.
S- Has one shell, shaped like a circle, so in total can hold 2 electrons.
P- has three shells, shaped like an infinity symbol, so in total can hold 6 electrons
D- has five shells, shaped, err, dunno how to describe it, can hold 10 electrons.
F- has 7 shells, um, even more dunno how to describe it, can hold 14 electrons
There doesn't only have to be one of each shell though. There can be two S levels, and one P level, and no D or F levels.
(search up electron configuration it'll have a chart of the order in which these come in)
Each layer will be stated as Number layer electron number.
For example, the first layer of electron level would be 1, because it's the first layer, S, because that's what the first layer is, and if it was completely filled, 2.
So, 1s2.
If you were going to add another level, which would also be a S level, but it only has one electron, you would say:
2s1,
because it's the second s level and has one electron in it.
And to put the two together, just say:
1s2, 2s1
NOTE: if you were going to add another level, it would be a P level, but it wouldn't be 3p something, it would be 1p something because it is the first electron level.
Another note: if you have three layers of electrons, or just six electrons, you would just say 1p6. (because the P orbital can hold 6 electrons)
The tin fork and knife, the copper coin, and the steel fence pole.
Explanation:
Those are both what people would call soft metals so they are malleable to the extent of probably not needing heavy duty equipment. It depends on you description of malleable because the steel fence pole could be malleable with the correct equipment and not snap in half if bent slowly enough.
The definition of malleable: (of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking.
But the glass table, marble sculpture and antique ceramic vase are nowhere near malleable because if you tried bending them they wouldn't bend but would shatter and break into pieces.
2) To change the reaction rate of slope B to look like slope A, simply add a catalyst to speed up the rate of reaction, giving you a higher amount of products in a shorter amount of time (line A)
Explanation:
1 and 2)Two things can alter the rate of a reaction, either the addition of a catylist which will not alter the composition of the products or reactants, but will accelerate the reaction time, or an increase in temperature will also increase the rate at which a reaction will occur.
You could choose temperature also and have the same result, it's your choice both are correct, but catalyst is the easiest.
