Question

part of the periodic table is shown. using the information from the chart what is the number of electrons for antimony? 122 51 71

Explanation:

Step1: Recall electron - atomic number relation

In a neutral atom, the number of electrons is equal to the atomic number of the element. The atomic number is the number of protons in the nucleus of an atom, and for a neutral atom, the number of electrons (which are negatively charged) is equal to the number of protons (which are positively charged) to maintain electrical neutrality.

Step2: Identify atomic number of Antimony

From the given part of the periodic table for Antimony (Sb), the number 51 is the atomic number (the number at the top, usually representing the atomic number).

Step3: Determine number of electrons

Since Antimony is a neutral atom (in its elemental state, not an ion), the number of electrons is equal to its atomic number. So, the number of electrons for Antimony is 51.

Answer:

51
