How can I make the atomic model of boron?

Answer 1

You can use craft cotton (or Styrofoam#""^"TM"#) balls, poster board, compass, glue, and string to make a model of a boron atom.

Here is a summary of the instructions from ehow.

Their instructions are for a sodium atom, but we can adjust them to make a model of any atom.

Step 1

You will need 11 large balls (5 of one colour for the protons and 6 of another colour for the neutrons) and 5 small balls for the electrons.

Glue the five protons and six neutrons into a ball, alternating between protons and neutrons as you go.

Step 2:

Cut a small ring and a large ring out of cardstock.

Use string to tie these rings in concentric circles around the nucleus (the picture below has a third ring for a sodium atom).

Step 3:

Glue two electrons to the inner circle and three to the outer circle.

Step 4:

Attach string to the outer circle for hanging, and display your 3D model of boron (the picture below is of sodium).

Answer 2

The atomic model of boron can be represented by its electron configuration and arrangement of protons and neutrons in the nucleus. Boron has 5 electrons arranged in the following configuration: 1s^2 2s^2 2p^1. The nucleus contains 5 protons and typically 5 or 6 neutrons, depending on the isotope. A visual representation can be created by depicting the nucleus surrounded by electron orbitals with appropriate labels indicating the number of electrons in each shell.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
