Exercises identify the group, period, and type (metal, nonmetal, or metalloid) of the Using the periodic table provided at the end of Lesson 4 of this book, elements below. Draw also the electron dot structure of each element. Element Group Period Type LEDS Aluminum Bromine Magnesium
Answer (1)
Answer:Here’s a breakdown of the elements you mentioned, including their group, period, type, and their electron dot structures (Lewis Dot Structures):### 1. Aluminum (Al)- **Group**: 13 (III-A)- **Period**: 3- **Type**: Metal- **Electron Dot Structure**: - Al: ••• (Aluminum has three valence electrons.)### 2. Bromine (Br)- **Group**: 17 (VII-A)- **Period**: 4- **Type**: Nonmetal- **Electron Dot Structure**: - Br: •••••• (Bromine has seven valence electrons.)### 3. Magnesium (Mg)- **Group**: 2 (II-A)- **Period**: 3- **Type**: Metal- **Electron Dot Structure**: - Mg: •• (Magnesium has two valence electrons.)### Summary Table| Element | Group | Period | Type | Electron Dot Structure ||-----------|-------|--------|--------|------------------------|| Aluminum | 13 | 3 | Metal | ••• || Bromine | 17 | 4 | Nonmetal | •••••• || Magnesium | 2 | 3 | Metal | •• |These details should help you understand the classification and electron configuration of each element! If you need any further information, feel free to ask.
