Answer:
1) Be.
2) [tex]B^{+}[/tex].
3) [tex]C^{2+}[/tex].
Explanation:
1) Be has an atomic number of 4, thus it has 4 electrons.
2) [tex]B^{+}[/tex] has atomic number 5, the positive charge on boron indicates that it has lost one electron. Thus, it has also 4 electrons.
3) [tex]C^{2+}[/tex] has atomic number 6. After the loss of 2 electrons now, it has also 4 electrons.
chemical symbols are used to represent the elements. The main advantage of using these symbols is that we don't need to write complete name of that element. It is the one or two letter designation of the elements.
Answer:
The chemical symbols for three different atoms or atomic cations with 4 electrons are Beryllium(Be), [tex]$B^+$[/tex], and [tex]$C^2+$[/tex]
Explanation:
A chemical symbol is a stenotype process of expressing an element. Alternatively of writing out the name of an element, we describe an element name with one or two letters.
- Beryllium(Be) is a element with atomic number 4.
- [tex]$B^+$[/tex] is a element with atomic number 5. The positive charge on boron symbolizes that it has dropped one electron. So, is considered as 4 electrons.
- [tex]$C^2+$[/tex] is a element with atomic number 6. After the decline of six electrons, it is represented as atomic number 4.
