Arrange the following as per instruction given in the bracket.
Cs, Na, Li, K, Rb (decreasing electronegativity)
The element below sodium in the same group would be expected to have a ______ (lower/higher) electro-negativity than sodium and the element above chlorine would be expected to have a ______ (lower/higher) ionization potential than chlorine.
Answer the following question using the data given below:
- Assertion: The nature of bond in HF molecule is ionic
- Reason: The electronegativity difference between H and F is 1.9.
In the table below, H does not represent hydrogen. Some elements are given in their own symbol and position in the periodic table while others are shown with a letter.
| IA | IIA | IIIA | IVA | VA | VIA | VIIA | O |
| 1 | 2 | 13 | 14 | 15 | 16 | 17 | 18 |
| Li | D | O | J | Ne | |||
| A | Mg | E | Si | H | K | ||
| A | C | F | G | L |
Select from the table.
- Which is most electronegative.
- How many valence electrons are present in G.
- Write the formula of the compound between B and H.
- In the compound between F and J what type of bond will be formed.
- Draw the electron dot structure for the compound formed between C and K.
