The elements x, y,and z have atoms with outer electron shell configurations containing 4,7 and 8 electrons respectively. state and describe the type of bonding which is likely to occur in the following cases: (1) between atoms of x ? (2) between atoms of y ? (3) between atoms of z ? (4) between one atom of x and four atoms of y?

Answers:

(1) Covalent

(2) Covalent

(3) None

(4) Covalent

Step-by-step explanation:

Element x is in Group 14 (carbon family); Element y is in group 17 (halogens); Element z is in Group 18 (noble gases).

Bonds between nonmetals are covalent bonds formed by sharing electrons.

(1) The x-x bonds are probably covalent bonds in a network solid, because it is difficult to form four covalent bonds between two atoms.

(2) Each y atom needs one electron to complete its octet. If they each share one electron, they will both have a octet. The y-y bond will be a single covalent bond.

(3) Each z atom is a noble gas. Noble gases do not form z-z bonds, because they already have an octet.

(4) Each xy₄ molecule will have four polar covalent x-y bonds pointing toward the corners of a regular tetrahedron.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
