Question

using the model and a periodic table, answer the following questions.
29 what period does this element belong in on the periodic table?
a 3 b 1 c 7 d 4 e 6 f 5 g 4

Explanation:

Answer:

To determine the period of an element from its Bohr model (electron - shell diagram), we use the rule that the period number of an element in the periodic table is equal to the number of electron shells (energy levels) that the atom has.

1. First, we count the number of electron shells in the given Bohr model:

• Looking at the diagram, we can see that there are 4 distinct electron shells (the concentric circles representing different energy levels for electrons).

1. Then, based on the relationship between the number of electron shells and the period number:

• Since the number of electron shells is 4, the element belongs to period 4.

Among the given options, option D is 4. So the answer is D.
