Step 1:Let's solve this step by step:
Step 2:: Understand Valence Electrons
Valence electrons are the electrons in the outermost shell of an atom, which participate in chemical bonding. These are typically the electrons in the highest energy level and subshells.
Step 3:: Analyze the Electron Configuration
- $$4p^{4}
Let's break down the given electron configuration:
Step 4:: Identify the Highest Energy Level
- $$4p^{4}
The highest energy level in this configuration is the 4th energy level (n = 4), which contains:
Step 5:: Count Valence Electrons
- $$4s^{2}$$ contributes 2 electrons
- 4p^{4} contributes 4 electrons
Step 6:: Calculate Total Valence Electrons
Total valence electrons = $$2 + 4 = 6
Final Answer
The element has 6 valence electrons.
