<u>Answer:</u> The element in fifth period of the periodic table having complete outer shell is Xenon.

<u>Explanation:</u>

Elements are distributed in 7 periods and 18 groups. Groups are the vertical columns and periods are the horizontal rows.

Element having complete outer shells are present in Group 18 of the periodic table. These elements are known as noble gases.

Element present in Period 5 and Group 18 of the periodic table is Xenon.

The atomic number of Xenon is 54.

Hence, the element in fifth period of the periodic table having complete outer shell is Xenon.

Covalent compounds are generally not very hard. Justify the statement.

Eduardwww [97]

Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.

<h3>COVALENT COMPOUNDS:</h3>

Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.

Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

Examples of covalent compounds are:

H2 - hydrogen
H2O - water
HCl - hydrogen chloride
CH4 - methane

Answer:

isotopes, there elements with a diffrent type atomic weight then the original, usally due to a higher amout of neutrons than the original. Some Isotopes are just as useable as the normal versions, but in some cases, such as Uranium, they can be even more radioactive than the original form
