Atom Lesson

What 4 categories make up periodic trends?

• Electrons, protons, neutrons, & nucleus

• Matter, mass, weight, & height

• Electronegativity, atomic radius, ionization energy, & electron affinity

• Elements, compounds, mixtures, & pure substances

Who created/founded the periodic table?

• Rutherford

• Dmitri Mendeleev

• Dalton

• Thompson

What is does the Lewis Dot represent?

• It represents the nucleus that has protons and neutrons

• It represents atoms

• It represents they connection between the electrons & the nucleus

• It represents the bond between the atoms in a molecule and the pairs of electrons that exist

What is a ion?

• An ion is one or more atoms that carry a positive or negative charge as a result of gaining an electron or loosing an electron

• An ion is a particle in the nucleus that will die, then come back to the nucleus

• An ion is a molecule that sits by itself in the nucleus

• An ion is an element

What are the three particles that make up an atom?

• Particle, nucleus, matter

• Matter, mass, weight

• Protons, neutrons, electrons

• Clouds, air, water

What is the structure of an atom?

• Everything is in the nucleus

• Every particle surrounds the nucleus and only air is in the nucleus of the atom

• There is no structure to an atom, it is just air

• Protons & neutrons are located in he nucleus, and electrons surround the nucleus of the atom

What does Bohr's model show?

• Bohr's model shows all particles in the nucleus of the atom

• Bohr's model shows the protons & neutrons in the nucleus & the electrons surrounding the nucleus

• Bohr's model shows only electrons of the atom

• Bohr's model shows that there isn't three particles to an atom

Is every element equal to its square?

• True

• False

When are ions formed?

• when the atom is ready

• When the atom loses and gains electrons

• When the atom gains neutrons

• When the atom gains protons

What is listed in a square of the periodic table?

• Just the atomic number

• Element name, weight

• Atomic mass, atomic number, symbol

• Name of element, atomic number, symbol, atomic mass
