Biology Unit 2 Lesson 1 FA Review

Atoms connected by covalent bonds share

• hydrogen ions

• ionic compounds

• pairs of electrons

• carbon and oxygen

The digram shows the particles that make up an atom. What is the name of the negatively charged particles shown in this model of an atom?

• proton

• electron

• prion

• neutron

From the information that two atoms have two different proton counts,

you can conclude that these atoms . . .

• belong to two entirely different elements

• represent different isotopes

• are likely to react violently with each other

• might be two ions of the same element

Identify a nonmetal on the periodic table

Identify a metal from the periodic table

Select all that apply:  What particle(s) are found in the center (core) of the atom? 

• Neutron

• Electron

• Proton

What is the name of the following atoms? (hint: look at the atomic number of the element on the periodic table)

An atom with 3 protons

What is the name of the following atoms?

(hint: look at the atomic number of the element on the periodic table)

An atom with 13 protons

 How does an atom become an ion?  (hint: Remember that an ion is an atom with a + or - charge)

Draw a bohr model of the atom for Oxygen

 (hint: there are 8 electrons; 2 in the first shell, and 6 in the outer shell)
