Explanation:
Argon atom has atomic number 18. Then, it has 18 protons and 18 electrons.
To determine the quantum numbers you must do the electron configuration.
Aufbau's principle is a mnemonic rule to remember the rank of the orbitals in increasing order of energy.
The rank of energy is:
1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7d
You must fill the orbitals in order until you have 18 electrons:
- 1s² 2s² 2p⁶ 3s² 3p⁶ : 2 + 2 + 6 + 2 + 6 = 18 electrons.
The last electron is in the 3p orbital.
The quantum numbers associated with the 3p orbitals are:
- = 1 (orbitals s correspond to = 0, orbitals p correspond to = 1, orbitals d, correspond to = 2 , and orbitals f correspond to = 3)
- can be -1, 0, or 1 (from - to + )
- the fourth quantum number, the spin can be +1/2 or -1/2
Thus, the six possibilities for the last six electrons are:
- (3, 1, -1 +1/2)
- (3, 1, -1, -1/2)
- (3, 1, 0, +1/2)
- (3, 1, 0, -1/2)
- (3, 1, 1, +1/2)
- (3, 1, 1, -1/2)
Hence, the correct choice is:
- = 1
- = 1
Answer:
this isn't a fair question...
you'll either get 2,3 or 4
not a nice question
> News sites give information about news or what is trending around the area or world (CNN, Fox, MSNBC, etc)
> Search engines is what allows you to look up websites (Google, Bing, Yahoo, etc)
> Social media AKA Social Networking sites is interaction social sites where you connect with various people from around the world. (Facebook, Twitter, Google+, etc)
>Apps is short for applications which is an application that has a specific function (Games, Music, Social networking)
So based on this, you answer is C. Social Media
Answer:
The printItem() method code is filled in the explanation, highlighted with bold font.
Explanation:
// ===== Code from file BaseItem.java =====
public class BaseItem {
protected String lastName;
public void setLastName(String providedName) {
lastName = providedName;
return;
}
// FIXME: Define printItem() method
/* Your solution goes here */
public void printItem() {
// TODO Auto-generated method stub
System.out.println("Last name: "+lastName);
}
}
// ===== end =====
