Question

directions: watch the video clip to complete the statements below. each atom has
the nucleus contains
o electrons have
o protons have a
o neurons have a
the nucleus has a
charge because the protons have the same
charge.
each atom is considered to be electrical
o in order for an atom to be neutral, it must have 1
for every proton.
o electrons are located
the nucleus.
protons and neutrons are
together and not fa apart.
the
is very small compared to the whole atom.
isotopes
isotopes are atoms with the same number of
but different numbers of
since isotopes of an element have different
of neutrons, they also have different
mass numbers.

Explanation:

1. Each atom has a nucleus and electrons. The nucleus contains protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have a neutral charge. The nucleus has a positive charge due to protons. Each atom is electrically neutral, needing one electron for every proton. Electrons are outside the nucleus. Protons and neutrons are bound together and the nucleus is small compared to the atom.
2. Isotopes are atoms with the same number of protons but different numbers of neutrons. Different numbers of neutrons lead to different mass - numbers.

Answer:

• Each atom has a nucleus and electrons.
• The nucleus contains protons and neutrons.
• Electrons have a negative charge.
• Protons have a positive charge.
• Neutrons have a neutral charge.
• The nucleus has a positive charge because the protons have the same charge.
• Each atom is considered to be electrically neutral.
• In order for an atom to be neutral, it must have 1 electron for every proton.
• Electrons are located outside the nucleus.
• Protons and neutrons are bound together and not far apart.
• The nucleus is very small compared to the whole atom.
• Isotopes are atoms with the same number of protons but different numbers of neutrons.
• Since isotopes of an element have different numbers of neutrons, they also have different mass numbers.
