Draw and show the electron arrangement of Boron, Nitrogen, Fluorine, and Phosphorus atoms.

1. Draw and show the electron arrangement of the following atoms:

a) Boron (5 electrons)
The electron arrangement for Boron is 2, 3.
To draw this, you would show a central nucleus, then:

• The first electron shell with 2 electrons.
• The second electron shell with 3 electrons.

b) Nitrogen (7 electrons)
The electron arrangement for Nitrogen is 2, 5.
To draw this, you would show a central nucleus, then:

• The first electron shell with 2 electrons.
• The second electron shell with 5 electrons.

c) Fluorine (9 electrons)
The electron arrangement for Fluorine is 2, 7.
To draw this, you would show a central nucleus, then:

• The first electron shell with 2 electrons.
• The second electron shell with 7 electrons.

d) Phosphorus (15 electrons)
The electron arrangement for Phosphorus is 2, 8, 5.
To draw this, you would show a central nucleus, then:

• The first electron shell with 2 electrons.
• The second electron shell with 8 electrons.
• The third electron shell with 5 electrons.

2. Copy and complete table 1.3 and use it to answer the questions that follow.

Table 1.3 is not provided in the image. Therefore, I cannot complete the table or answer questions a) and b) based on it. Please provide Table 1.3 for further assistance.
