(a)
Interpretation:
The period and group number of element oxygen are to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.

- Please help thanksarrow_forwardThe most common isotope of oxygen has a mass number of 16, but two other isotopes having mass numbers of 17 and 18 are also known. For each isotope, give the following information: (a) the number of protons; (b) the number of neutrons; (c) the number of electrons in the neutral atom; (d) the group number; (e) the element symbol using superscripts and subscripts.arrow_forwardA neutral atom of chlorine-37 has protons, neutrons, and electrons. Silicon and lead are an example of two elements that belong to the same Select one: class. gender. group. period. Which set below includes only alkali metal elements? gallium, germanium, iron, barium, tellurium lithium, sodium, potassium, rubidium, francium magnesium, gallium, flluorine, mercury, neptunium radium, polonium, actinium, platinum, seleniumarrow_forward

(b) Radioactive americium-241 is used in house-hold smoke detectors and in bone mineral analysis. Give the number of electrons, protons, and neutrons in an atom of americium-241.arrow_forward
- One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.arrow_forward2.96 Use the web to look up the density of different forms of steel, such as stainless steel or magnetic steel, and discuss whether or not the differences in the densities follow what might he predicted by looking at the periodic properties of elements.arrow_forwardThe photo here depicts what happens when a coil of magnesium ribbon and a few calcium chips are placed in water. (a) Based on these observations, what might you expect to see when barium, another Croup 2A element, is placed in water? (b) Give the period in which each element (Mg. Ca, and Ba) is found. What correlation do you think you might find between the reactivity of these elements and their positions in the periodic table?arrow_forward
