Question
Use the periodic table to answer the question.
An illustration shows the periodic table of elements. The elements in the periodic table are arranged in groups (columns numbered 1 through 18) and periods (rows numbered 1 through 7) such that the atomic number increases along a period from left to right. The elements are divided into the following categories: · Alkali metals · Alkaline earth metals · Transition metals · Post-transition metals · Lanthanides · Actinides · Metalloids · Nonmetals · Noble gases · Unknown The elements are also classified on the basis of their physical states as follows: · Solid · Liquid · Gas · Unknown The element sulfur is enlarged with the following properties. · Chemical symbol: S · Name: Sulfur · Atomic Number: 16 · Atomic mass: 32.06 · Common oxidation states: 6, 4, 2, negative 2 · Electronegativity: 2.58 · Ionization energies: 999.589 · Electron configuration: [Ne] 3s2 3p4

To determine how an atom of the element strontium (Sr) is likely to change during bonding, we need to consider its position on the periodic table and its electron configuration.
Strontium is located in group 2 (alkaline earth metals) of the periodic table. Elements in group 2 have two valence electrons in their outermost energy level. These valence electrons are the ones involved in bonding with other atoms.
Considering strontium's electron configuration, it has the electron configuration [Kr] 5s2. This means that it has two valence electrons in its 5s orbital.
When strontium forms a chemical bond, it is most likely to give up its two valence electrons, becoming a positively charged ion. This is because by giving up its valence electrons, strontium can achieve a stable electronic configuration similar to that of the closest noble gas, which in this case is krypton (Kr).
Therefore, the correct response is: It will give up electrons, forming a positive ion.
Based on its electron configuration and position on the periodic table, an atom of strontium (Sr) has 2 electrons in its outermost energy level. These electrons are located in the 5s orbital.
During bonding, atoms tend to either gain or lose electrons to achieve a stable electron configuration. Strontium will most likely give up its 2 outermost electrons, resulting in a positive ion.
Therefore, the correct answer is: It will give up electrons, forming a positive ion.
