Question

part 3: vocabulary word bank — match the word to its correct definition
word bank:
● isotopes
● average atomic mass
● mass number
● periodic table
● quarks
● electric cloud
definitions:
a) the weighted average mass of all naturally occurring isotopes of an element.
b) atoms of the same element with different numbers of neutrons.
c) the total number of protons and neutrons in an atoms nucleus.
d) a chart that organizes elements by increasing atomic number and similar properties.
e) subatomic particles that combine to form protons and neutrons.
f) the region around the nucleus where electrons are most likely to be found.

Explanation:

Isotopes are atoms of the same element with different neutron - counts. Average atomic mass is the weighted average of an element's isotopes' masses. Mass number is the sum of protons and neutrons in a nucleus. The periodic table organizes elements by atomic number and properties. Quarks are subatomic particles that form protons and neutrons. The electric cloud is the region around the nucleus where electrons are likely found.
