Of the well-characterized elements of group 7A, which would exhibit the following properties? It reacts with the alkali metals (
dezoksy [38]

Answer:

a. fluorine

Explanation:

Fluorine is the element of group 17 and period 2. The electronic configuration of the element is 1s^22s^22p^5.

Stable oxidation state = -1 of fluorine as it gains one electron to gain noble gas configuration.

With alkali metals, which have oxidation state of +1 form ionic compound of the form, MX where X is F.

Among the halogens, fluorine forms the most stable halide because of the comparable size of the hydrogen and fluorine. Thus, it is the weakest acid when compared with other hydrogen halides.

Fluorine is the most reactive in the halogen series and thus, combines with most of the elements.

Fluorine forms inter-halogen compounds of form XA only. Example - ClF.

Hence, option a is correct.

Which concept describes the formation of four equivalent, single, covalent bonds by carbon in its compounds that resembles metha
Montano1993 [528]
Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.

list the following from greatest to least mass: 1 mol of H2, 2 moles of K, 3 moles of Mg, and 4 moles of He
Leya [2.2K]
H₂ = 2 g/mol

1 x 2 = 2 g of H₂
________________________

K = 39.09 g/mol

2 x 39.09 = 78.18 g of K
________________________________
 
Mg = 24.3 g/mol

3 x 24.3 = 72.9 g of Mg
_________________________________

He = 4 g/mol

4 x 4 = 16 g of He
___________________________________

Order :  K , Mg , He  and H₂


hope this helps!
