Which element behaves the MOST like calcium and why?

Ba, because it is in the same group and has same number of valence electrons.

K, because it is in the same period and only has one less valence electron.

Br, because it is in the same period and has more valance electrons.

Sc, because it is in the same period and has one more valence electron.

What is the difference between these three isotopes of carbon?

They have different atomic masses.

They have different atomic numbers.

They have different numbers of protons.

They have different numbers of electrons.

The diagram shows the location of two elements in the periodic table.

Element A is a solid, and element B is a gas at room temperature.

Element A is a non-metal, and element B is a metal.

Element A forms a 2- ion, and element B forms a 1+ ion.

Element A has two valence electrons, and element B has one valence electron.

Physical Properties of Two Elements Element 1: Shiny, Can be hammered into different shapes or bent without breaking Element 2 : TransparentBrittle and shatter when hammered In which region of the periodic table are Elements 1 and 2 MOST LIKELY located?

Element 1 is in Region C, and Element 2 is in Region B.

Elements 1 and 2 are both in Region B.

Elements 1 and 2 are both in region C.

Element 1 is in region A, and element 2 is in Region C.

The noble gas neon is used for filling neon signs. Like other noble elements, it has a full octet (complete outer energy level) of electrons, which makes the gas

unlikely to combine with other elements

Atomic massfreeze at room temperature

Atomic numberreact with other gases in the air

solidify at standard pressure and temperature

What pattern can you observe in the Periodic Table regarding the ions that elements tend to form?

Elements tend to form positive ions as the become more metallic.

Elements tend to form negative ions as they increase in electrical conductivity.

Elements tend to form positive ions as their melting and boiling points decrease.

Elements tend to form negative ions as they decrease in number of valence electrons.

Using the information in the Periodic Table, how would you rank the elements rubidium (Rb), antimony (Sb), and iodine (I) in order of increasing number of valence electrons?

Antimony has a lower number of valence electrons than iodine but a greater number than rubidium.

Antimony has a greater number of valence electrons than iodine but a lower number than rubidium.

Iodine has a lower number of valence electrons than rubidium but a greater number than antimony.

Rubidium has a greater number of valence electrons than antimony but a lower number than iodine.

What does the atomic number represent?

the number of protons in the nucleus of an atom

the number of neutrons in the nucleus of an atom

the number of protons and neutrons in the nucleus of an atom

the number of electrons in the energy levels outside of the nucleus
