Most molecules are composed of what? one or more elements two or more elements three or more elements four or more elements Countdown 10

Why can metals bend without breaking? Metals contain positively charged ions. Metals contain constantly moving electrons. Metals contain ionic bonds. Metals contain moving ions. Countdown 10

How are electrons in an atom organized? energy levels valence levels groups periods Countdown 10

What are the only parts of an atom that make chemical bonds? protons in the nucleus neutrons in the nucleus electrons in the nucleus valence electrons Countdown 10

What is the same within each group on the periodic table? number of protons number of electrons number of atoms number of valence electrons Countdown 10

Why don’t noble gases normally form chemical bonds? They have 2 valence electrons. They have a full outermost energy level. They have an empty outer level. They have 8 protons. Countdown 10

What is the charge of a sodium ion with 11 protons and 10 electrons? 1+ 2+ 1– 2– Countdown 10

What ending is used for the names of negative ions formed when atoms gain electrons? -ade -ide -ate Countdown 10

What can group numbers on the periodic table help you determine? the number of valence electrons the number of electrons the number of protons the number of neutrons Countdown 10

What is the smallest particle into which a covalently bonded compound can be divided and still be the same compound? molecule atom electron proton Countdown 10

What allows metals to bond? overlapping outer energy levels a low number of valence electrons a large number of valence electrons ions Countdown 10

Which of the following properties of a metal means that it can be drawn into wires? electrical conductivity malleability ductility flexibility Countdown 10

Which of the following represents the number of protons in an atom? proton number atomic number covalent number nuclear number Countdown 10

What do atoms gain, lose, or share when they bond? protons neutrons electrons atoms Countdown 10

What do metal atoms form when they lose valence electrons? negative ions positive ions covalent bonds atomic bonds Countdown 10

What is the joining of atoms to form new substances? chemical bonding bonding joining chemicals bonding atoms Countdown 10

What do you call an interaction that holds two atoms together? chemical hold chemical bond chemical interaction bond of chemicals Countdown 10

What do you call a bond that forms when electrons are transferred from one atom to another? compound bond ionic bond crystal bond atom bond Countdown 10

What are charged particles that form when atoms gain or lose electrons? particle atoms atomic ions bonds ions Countdown 10

When atoms gain electrons during chemical changes, what charge do they have? positive charge neutral charge negative charge chemical charge Countdown 10

What is the most important factor in determining how an atom will bond? the number of protons the number of neutrons the number of electrons in the innermost energy level the number of electrons in the outermost energy level Countdown 10

How many valence electrons does helium need to have a filled outermost energy level? 1 2 4 8 Countdown 10
