47
Q

Why is the mass number called the “mass” number?

How is the mass number of an isotope expressed in the name of an atom?

A

It is said at the end. Hydrogen-1.

50
Q

Can the number of protons change in an element?

A

No (that would change the element into a whole new element).

51
Q

What are isotopes?

A

Elements that have the same number of protons, and the same location on the periodic table, it just has a different number of neutrons.

52
Q

In a neutral atom, how does the number of electrons compare to the number of protons?

A

The number of protons and electrons are the same.

53
Q

What are Cations?

A

Negatively charged ions.

55
Q

In what region of the periodic table are “multiple ion” elements located?

A

Transition elements and group 14.

56
Q

What element comes first in the name and formula of the compounds–the metals or the nonmetals?

A

The Metals.

57
Q

Describe how the names of the nonmetal elements are changed when they are in their anion form?

A

The anion’s name is changed by adding an “ide” at the end.

58
Q

What do you add to the name of an atom that can form more than one ion?

A

Roman numerals –PbO–Lead(II) oxide.

59
Q

What do the Roman Numerals in the compounds indicate?

A

The charge on the cation.

60
Q

What is carbon dating?

A

the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.

61
Q

What materials can be carbon dated?
