Options

A. low IE and high EA
B. low IE and low EA
C. high IE and low EA
D. high IE and high EA

Explanation

To solve the question "An element with high electronegativity has:", we will go through the concepts of electronegativity, ionization energy, and electron affinity step by step.

### Step-by-Step Solution:

1. **Understanding Electronegativity**:
- Electronegativity is defined as the tendency of an atom to attract shared pairs of electrons towards itself in a chemical bond.

**Hint**: Remember that electronegativity is about how strongly an atom can pull electrons in a bond.

2. **Relation to Ionization Energy**:
- Ionization energy is the energy required to remove an electron from an isolated gaseous atom. Generally, elements with high electronegativity tend to have high ionization energy because they hold onto their electrons tightly.

**Hint**: Think about why an atom that wants to attract electrons would also resist losing its own electrons.

3. **Relation to Electron Affinity**:
- Electron affinity is the energy change that occurs when an electron is added to a neutral atom to form a negative ion. Elements with high electronegativity typically have high electron affinity, meaning they release a significant amount of energy when they gain an electron.

**Hint**: Consider how an atom that is eager to gain electrons would also be favorable in terms of energy release when it does so.

4. **Trends in the Periodic Table**:
- As you move from left to right across a period in the periodic table, both ionization energy and electron affinity tend to increase. This is because the atomic radius decreases, leading to a stronger attraction between the nucleus (protons) and the electrons.

**Hint**: Recall that smaller atoms with more protons can attract electrons more effectively.

5. **Conclusion**:
- Therefore, an element with high electronegativity will have both high ionization energy and high electron affinity. This means that it is energetically favorable for the atom to both hold onto its own electrons and attract additional electrons.

**Final Answer**: An element with high electronegativity has high ionization energy and high electron affinity.
