b
What is the difference between an atom and an ion?
a.) An atom has more neutrons than an ion.
b.) An atom has a neutral charge because it has an equal number of protons and
electrons, whereas an ion has a positive or a negative charge.
c.) An ion has a higher atomic number than an atom.
d.) An ion has a neutral charge because it has an equal number of protons and
electrons, whereas an atom has a positive or a negative charge.
e.) An atom has a higher atomic number than an ion.
d
Which of the below statements accurately describes the components of an atom?
a.) Neutrons, which have no charge, occupy the nucleus. Positively charged protons
and negatively charged electrons orbit the nucleus in shells.
b.) Protons, which have a positive charge, and electrons, which have a negative charge,
occupy the nucleus. Neutrons with no charge orbit the nucleus in shells.
c.) Protons, which have a positive charge, and neutrons, which have a negative charge,
occupy the nucleus. Electrons with no charge orbit the nucleus in shells.
d.) Protons, which have no charge, occupy the nucleus. Positively charged neutrons
and negatively charged electrons orbit the nucleus in shells.
,e.) Protons, which have a positive charge, and neutrons, which have no charge, occupy
the nucleus. Negatively charged electrons orbit the nucleus in shells.
a
How does an atom become a positive or a negative ion?
a.) An atom becomes a positive ion by losing an election; it becomes a negative ion by
gaining an electron.
b.) An atom becomes a positive ion by losing a neutron; it becomes a negative ion by
gaining an electron.
c.) An atom becomes a positive ion by gaining a proton; it becomes a negative ion by
losing a proton.
d.) An atom becomes a positive ion by gaining an electron; it becomes a negative ion by
losing an electron.
