Question

drawing bohr diagrams
while the bohr model is an overly simplistic model, it is a useful place to start understanding how electrons are located in different energy levels of an atom.
rules for arranging electrons:
electrons fill energy levels starting closest to the nucleus.

1. the first energy level can hold up to 2 electrons.
2. the second energy level can hold up to 8 electrons.
3. the third energy level can hold up to 8 electrons.
4. the fourth energy level can hold up to 18 electrons.

sketch an atom:
write 5 p in the nucleus for 5 protons.
write 6 n in the nucleus for 6 neutrons.
draw 2 electrons in the 1st energy level.
draw 3 electrons in the 2nd energy level.
name of element = ______________

Explanation:

El número atómico de un elemento está dado por el número de protones en su núcleo. En este caso, el átomo tiene 5 protones. El elemento con número atómico 5 es el boro.

Answer:

Boro
