From its position in the periodic table, one would predict that the element potassium has the following property: a. more active than lithium b. enters into chemical reactions by taking electrons from other elements c. would react with such elements as sulfur or iodine to form covalent compounds d. has less attraction for its outer electron than does rubidium

more active than lithium

Explanation:

The position of potassium is in the first group, below lithium.

a) Due to is larger size, it can give electron easily as compared to lithium thus is more reactive than lithium.

b) As it belongs to first group, it has one electron in its outermost shell, so it gives this electron easily to form positive ion. Hence it does not enter reaction by taking electrons.

c) as it can give electrons easily, so it is highly electropositive element. It will form ionic compounds with non metals like iodine.

d) due to its smaller size than rubidium, it will have more attraction for its outer electron.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
