In each box please fnd and then write the correct element by name, its atomic number, atomic mass, and atomic symbol. Use the informat ion in each box to help you. 16 B Bromine 14.01 amu 55 4 РЬ Chlorine 77 Ne Gold 16.00 amu I don't have a neutron Zn 259.00 amu 40.08 amu

When reading the periodic table there are Periods (rows) and Groups/ Families (columns).   Describe what the group number represents (the numbers at the top of each column)  Describe what the period number represents (the number on the far left side of each row)

atomic number is the number of  1. radioactive isotopes of an element 2. protons in an atom of an element 3. protins and electrons in an atom of an element 4. neutron in an atom of an element

In the periodic table, elements are organized based on their atomic numbers and properties. One of the most significant features of the periodic table is the periodicity in the properties of elements. For example, elements in the same group often exhibit similar chemical behaviors due to having the same number of valence electrons. Consider the halogens, which include fluorine, chlorine, bromine, iodine, and astatine. These elements are found in Group 17 and are known for their high reactivity, particularly with alkali metals and alkaline earth metals, forming salts. Their reactivity decreases as you move down the group. Which of the following statements best explains the reason for the decreasing reactivity of halogens as you move down Group 17? A. The atomic radius decreases, making it harder for the halogens to gain electrons. B. The atomic radius increases, making it easier for the halogens to gain electrons. C. The ionization energy increases, making it easier for the…
