Answer:
The answer is covalent bond
Explanation:
when oxygen atom and two hydrogen atoms are combined, water molecule is formed according to the equation;
2H2 + O2 ==> 2H2O
Water is a covalent compound.
A covalent bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full outer shell, corresponding to a stable electronic configuration.

The only metalloid located in the sixth period of the periodic table is Astatine. Others are located in previous periods.
Answer:
Explanation:
We classify the behaviours of electrolytes based on their electrolytic conduction. This is what makes them breaks down when in aqueous solutions with water.
A strong electrolyte is one that ionize completely when in aqueous solutions. Their ionization can be shown below using appropriate chemical notation:
An example of a strong electrolyte is NaCl:
NaCl
→ Na⁺
+ Cl⁻
Such reactions have a single forward arrow. Since they ionize complete, they have a large amoung of ions present in their aqueous form and would readily conduct.
A weak electrolyte is made up of compounds that ionize partially or slightly in their aqueous solution. The amount of ions produced per mole of compounds is relatively small compared to those of strong electrolytes. Examples ae organic acids, weak bases, and water. This ionization is shown below for methanoic acid:
HCOOH
⇄ HCOO⁻
+ H⁺
This sort of reaction is an equilibrium reaction. This is why we have the double arrow.
None electrolytes do not ionize at all in aqueous solutions and they produce no ions.
