Back to all questionsQuestion 2
Consider the section of the periodic table given below:
| Group numbers | 1A 1 | IIA 2 | IIIA 13 | IVA 14 | VA 15 | VIA 16 | VIIA 17 | O 18 |
|---|---|---|---|---|---|---|---|---|
| Li | D | O | J | Ne | ||||
| A | Mg | E | Si | H | K | |||
| B | C | F | G | L |
Some elements are given in the above table in their own symbol and position in the periodic table, while others [shaded] are shown with a letter. With reference to the table:
(i) Which is the most electronegative?
(ii) How many valence electrons are present in G?
(iii) Write the formula of the compound between B and H.
(iv) In the compound between F and J, what type of bond will be formed?
(v) Draw the electron dot structure for the compound formed between C and K.
(i) J is the most electronegative.
(ii) G has 5 valence electrons.
(iii) B2H is the name of the compound between B and H.
(iv) Covalent bond will be formed between F and J.
(v) Electron dot structure for the compound formed between C and K is shown below:
