H : H
The two dots between H denote the shared pair of electrons.
The electron dot formula or Lewis structure for hydrogen gas (H2) consists of two hydrogen atoms sharing a pair of electrons between them. Each hydrogen atom contributes one electron to the shared pair, forming a single covalent bond. The structure is represented as H:H or H-H, with a single bond between the hydrogen atoms.
H - Br There should be one dot to the right of the Hydrogen atom(H), sharing a bond with a dot to the left of the Bromine atom (Br). Then add two dots on each other side of the Br. In total, there should be one dot around H and seven dots around Br.
The Lewis Dot Structure for Helium (He) is,* He :When Helium wants to bond with another atom, it is one of the three exceptions to the octet rule.*Ex. He:HeWhile most other elements have to bond with octets. Such as Hydrogen, Carbon, and Nitrogen.*H-C_=N:Hydrogen bonds once with Carbon and Nitrogen and Carbon have to make an octet so the three lines (_=) and the same as the dot structure (:::) The two valence electrons on the left side of the Nitrogen atom cannot join the Carbon and Nitrogen bond because there is no way two atoms can have a quadruple bond.Remember that each line equals to two electrons. So Nitrogen and Carbon have 8 electrons that they share, satisfying the octet rule.
H-H or H:H depending on what you and your professors prefer.
Yes, this chemical reaction is correct. It shows the combination of hydrogen gas (H2) and chlorine gas (Cl2) to form hydrogen chloride gas (HCl) through a chemical reaction.

The correct answers are: Ag+ and Cu+2.
Yes, this chemical reaction is correct. It shows the combination of hydrogen gas (H2) and chlorine gas (Cl2) to form hydrogen chloride gas (HCl) through a chemical reaction.
I believe the correct formula is Cu-H2-O2.
A Lewis dot structure tells chemists a great deal about the structure and bonding in a molecule. It is used to understand what types of bonds exist in the molecule (whether there are single, double or triple bonds, for instance). It can also be used to determine how molecules will react and what some of their properties will be. It can also be used to determine the shape of a molecule and the position of each of the atoms in the molecule (to do this you must also use something called VSEPR, or valence shell electron repulsion theory along with the Lewis dot structure).See the Related Questions to the left for how to draw a Lewis dot structure of any molecule.
No, the correct equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is: Mg + 2HCl → MgCl2 + H2. This reaction produces magnesium chloride (MgCl2) and hydrogen gas (H2).
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
The correct balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl → ZnCl2 + H2 This reaction produces zinc chloride (ZnCl2) and hydrogen gas (H2).
