With a pencil. Or a pen; I'm that confident.
The best suggestion I can give to you is to follow the given directions; they seem pretty straightforward to me.
I believe it is Chlorine? Please correct me if I'm wrong.
The correct electron configuration would be 3d5 as each orbital in the 3d sublevel can hold up to 2 electrons, and we have 5 electrons to place in this sublevel.
six valence electrons
No, MgCl3 is not a valid compound. The correct compound using magnesium (Mg) and chlorine (Cl) would be MgCl2. MgCl2 is an ionic compound where magnesium loses two electrons to become a Mg2+ cation, and chlorine gains one electron to become Cl- anion.
When magnesium (Mg) and chlorine (Cl) form a compound, magnesium will typically lose two electrons and chlorine will gain one electron to achieve a stable electron configuration. The resulting compound is magnesium chloride (MgCl2), where one magnesium ion is bonded to two chloride ions through ionic bonds.
yes, chlorine has 7 valence electrons
The correct electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5. This notation represents the distribution of electrons in the various energy levels and sublevels of the chlorine atom.
the outer electron shell has 7 electrons. its full configuration is 2.8.7
I believe it is Chlorine? Please correct me if I'm wrong.
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
The electron dot formula for hydrogen chloride (HCl) shows one bond between hydrogen and chlorine with two lone pairs of electrons around chlorine. So, it would be written as H:Cl with two dots around the Cl to represent the lone pairs.
The correct answer is: The electrons farthest away from the nucleus... chris ellis
The correct electron configuration would be 3d5 as each orbital in the 3d sublevel can hold up to 2 electrons, and we have 5 electrons to place in this sublevel.
The correct electron configuration for an element with 5 electrons, which is boron (B), is 1s² 2s² 2p¹. This indicates that the first energy level (1s) contains two electrons, the second energy level (2s) contains two electrons, and one electron is in the 2p subshell. Thus, the total adds up to five electrons.
