Atomic Structure True-False

A science team has found errors in its atomic-structure notes. For each statement, choose True or False. For false statements, rewrite the incorrect part to make it accurate.

True or False?

Select one answer for each statement. Use what you know about particle charge, location, atomic number, isotopes and relative mass.

1.A proton has a positive charge and is found in an atom’s nucleus.
TrueFalse
2.A neutron has no electrical charge and is found in the nucleus.
TrueFalse
3.Electrons have a negative charge and occupy regions around the nucleus called shells or energy levels.
TrueFalse
4.The atomic number of an element tells you how many neutrons its atoms have.
TrueFalse
5.Every atom of the same element has the same number of protons.
TrueFalse
6.Isotopes are atoms of the same element with different numbers of neutrons.
TrueFalse
7.The first electron shell can hold a maximum of two electrons.
TrueFalse
8.Nearly all the mass of an atom is concentrated in its tiny nucleus.
TrueFalse
9.An electron has about the same mass as a proton.
TrueFalse
10.A neutral atom has equal numbers of protons and electrons.
TrueFalse
11.Most of an atom’s volume is empty space, rather than solid matter packed into the nucleus.
TrueFalse
12.The relative atomic mass of an element is linked to the weighted average masses of its naturally occurring isotopes.
TrueFalse
