It's quite hard to draw and does not follow normal bonding laws but:
H2>B<H2>BH2
The < represents a bond to one H bond above and one below.
There are two types of B - H bonds: where the terminal B-H bonds are standard B:H, and where the middle B-Hs involves 2 centre 3 electron bridging
The Lewis structure of BeH2 would show beryllium in the center with two hydrogen atoms bonded to it, each sharing a pair of electrons. Beryllium would have no lone pairs of electrons and would have a formal charge of 0.
H-Be-H. This is an exception to the octet rule as there are only four electrons around the beryllium atom.
On first principles you would expect BeH2 to be an exception as shown above, and recently gas phase molecular BeH2 has been confirmed to be a linear molecule. However solid BeH2 is normally encountered is amorphous white solid and has a polymeric structure with 3 centre 2 electron bonds, so called banana bonds. These break all the rules we use in drawing Lewis structures. Boron hydrides are similarly electron deficient and also can form these 3 centre banana bonds. This demonstrates that the electron deficient Be and B atoms in the hydrides are able to make use of the electrons that are around in order to get closer to the octet even though they can never achieve it.
The Lewis structure for Be2 is nonexistent. A bond between two Be atoms will not form according to molecular orbital theory.

lewis structure of Cl2O7
Lewis structure was created in 1916.
CH4 is symbol for Methane.It is non polar.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.
Beryllium hydride.

The Lewis dot structure of the bicarbonate ion (HCO3-) consists of one hydrogen atom, one carbon atom, and three oxygen atoms. The carbon atom is double-bonded to one of the oxygen atoms and has a single bond with the other two oxygen atoms. Each oxygen atom has two lone pairs of electrons around it.
Yes, XeF4, or xenon tetrafluoride, has a Lewis structure.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.

The Lewis structure of K2O consists of two potassium (K) atoms bonding with one oxygen (O) atom. The oxygen atom will form a double bond with one of the potassium atoms, while the other potassium atom will have a single bond with the oxygen atom. This arrangement allows both potassium atoms to have a full outer shell of electrons.

The maximum number of electrons in a Lewis structure is eight, which is an octet of electrons.
