The crystal structure of sodium chloride NaCl is formed by the bonding of sodium ions Na - and chloride ions Cl -. Which of the four basic forces of the universe holds these ions together? The diagrams show part of the periodic table of the elements. The shaded areas represent a general trend in the number of valence electrons in the elements. The lighter shading indicates fewer valence electrons and the darker shading indicates more valence electrons.

Which diagram BEST shows the relationship between the elements and the number of valence electrons? Magnesium Mg , calcium Ca and strontium Sr have similar chemical properties. These similarities result mainly from which other similarity between these three elements? Based on the periodic table of the elements, which of these elements has properties MOST similar to calcium Ca? Plutonium Pu decays according to the reaction shown.

What is the identity of radioisotope X? The Sun produces energy when four hydrogen nuclei fuse to form one helium nucleus.

This process can be summarized by Which statement correctly describes this process? The isotopes of hydrogen react, forming the helium element, as shown. The Sun produces energy when four hydrogen nuclei fuse to form a nucleus of helium. This process can be summarized by energy. Which one affirmation describes this process correctly? One kilogram of uranium can produce as much energy as 16, kilograms of coal. Why is the energy output for uranium so much greater than the energy output for coal?

Uranium is extremely radioactive and gives off higher electromagnetic radiation than burning coal. Half of a sample of cobalt decays after 5. Half of a sample of iodine decays after 8.

Kieran collected the data below during an experiment that modeled the half-life of a radioactive isotope. He began with 50 pennies turned face up in a box to represent the. He shook the box five times to represent radioactive decay, then removed pennies that had turned over after each shaking.
