Answer:
100% medium
Explanation:
Since you got all Hh which equals medium it means all are going to be that.
Answer:
100% med
Explanation:
Answer:
177.53 grams
Explanation:
To find this, change the density equation from to , doing this will allow you to multiply your given density (0.789 g/cm^3) by your given volume (225cm^3), giving your mass of 177.53 grams.
B) 87 g
C) 270 g
D) 349 g
I can't figure out the answer.
Answer:
B) 87g

Do you know how to find valence electrons? The amount of valence electrons that an element has depends on its group number, with an exception towards transitional elements.
For example, Oxygen is in group 16, which makes it have 6 valence electrons. Group 1 has 1, group 2 has 2, group 13 has 3, group 14 has 4, and so on.
What about transitional elements? The elements ranging from group 3 until 11 have different valence electrons because (advanced) if you look at their electron configuration, they have d orbital electrons (they can be edited), which gives them a varied valence configuration.
1. Iodine: Group 17 - 7 valence electrons Calcium: Group 2 - 2 valence electrons Chlorine: Group 17 - 7 valence electrons Sodium - Group 1 - 1 valence electron Neon - Group 18 - 8 valence electrons Copper - Group 11 - *Copper is a transitional element!* Those within group 11 usually have either 1 or 2 electrons. Your teacher did not specify which copper he's asking, so you could say that there is Copper (I), which has 1 valence electron, and also Copper (II), which has 2 valence electrons.
Moving to your second question, to see how many electron shells an element has, you look at where they are in their period (horizontal row)
For example, oxygen is in period 2, therefore, it has two electron shells. Period 1 has 1, period 2 has 2, period 3 has 3, and so on.
1. 1. Iodine: Period 5 - 5 electron shells Calcium: Period 4 - 4 electron shells Chlorine: Period 3 - 3 electron shells Sodium - Period 3- 1 electron shells Neon - Period 2 - 2 electron shells Copper - Period 4 - 4 electron shells

Answer:
14 electrons can occupy the f sub level
Explanation:
Electronic configuration is the short representation which we use to represent the structure of an atom.
Atomic number of phosphorus is 15 so it has 15 electrons.
The electronic configuration of Phosphorus is given as
Here the superscript number represents the electrons 2 + 2 + 6 + 2 + 3 = 15 electrons of Phosphorus
Orbital diagram too is used for this purpose.
A circle or a square is used to represent an orbital.
This is the orbital diagram of Radon (atomic number -86)
Each orbital occupies 2 electron.
Shells are named using letters K, L, M, N and so on or using numbers 1, 2, 3, 4 etc.,
The number of electrons, a shell can accommodate is found using formula where n is the number of the shell.
Shell 1 contains subshell s
Shell 2 contains subshell s, p
Shell 3 contains subshell s, p, d
Shell 4 contains subshell s, p, d, f
Subshells or sub level are represented by letters s, p, d, f, g, h, i and so on.
s contains 1 orbital with 2 electrons
p subshell contains 3 orbital with 6 electrons
d with 5 orbitals and 10 electrons
f with 7 orbitals and 14 electrons.
