Unit 9/10

periodic table and simple atoms Vocab

QuestionAnswer
a negatively charged ion is called? Anion
The mass of the protons plus the mass of the neutrons equals _______? atomic mass
What do the letters on the periodic table sybolize atomic name
Every atom is arranged on the periodic table by counting its number of PROTONS. this number is called ______? atomic number
The horizontal rows on the Periodic table are called _______? (this row also tells us how many orbitals shells the atom has) atomic period
an abbreviation of each atom is printed on the periodic table and is called the... atomic symbol
The 2nd most recent model of an atom was discovered by and named after what man? This is the model we use to draw atoms on. Bohr Model
What are positively charged ions are called? Cation
When atoms are bonded by sharing of electrons the bond is named...? Covalant Bond
the rings or zones where the atom's electrons are stored are called? Electron shells (orbits)
The soft, silvery-white, solid, metallic elements, with 1 electron in their outer shell, that are super reactive are known as what group? It will always form a cation. the Alkali metals
The group or family that is a silvery metallic, reactive, solid, and has 2 electrons in its outer valence shell is called? It will always form a cation. the Alkaline Earth Metals
What group has 3 electrons in its outer shell and is composed of a metals and a metalloid? It will always form a cation. Boron Family
What group loves to make covalent bonds, is flexible at bonding and has 4 electrons in their outer shell? Carbon Family
What group needs 3 electrons to form an octet and has 5 electrons in the outer shells and is a mix of metals, nonmetals and metalloids Nitrogen family
what group has 6 electrons in the outer shell and is a combination of metals and metalloids? the oxygen family
what group is highly reactive and creates salts and has 7 electrons in its outer shell plus requires one electron to fill the octet rule, and has a very high/strong electron affinity. the Halogens
What group has a full octet and does not combine with other atoms? the Noble gases
a bond created by two atoms where one atom has a low electron affinity and one atom has a high electron affinity. The one with a high affinity will steal the electrons from the lower one to complete its octet. ionic bond
How do you know how many electrons are in the "outer bonding shell" of any atom? by the Family number (skipping the transition metals)
when an atom looses a neutron but still is the same atomic name it is called.... Example: Carbon 12 and Carbon 14 isotope
The outer most shell of all atoms is called...? hint:this is also the reason that the atom will bond due to the number of electrons in this outer most ring. valance electrons
Draw a lewis dot structure of an atom your teacher gives you Do
Draw a bohr model of an atom your teacher gives you Do- showing all subatomic particles and charges
Define the three main subatomic particles and know their charges. Protons, neutrons and electrons. BSD PS 1A 02 DO
Navigate the Periodic table to determine what atom has 6 electrons in it's outer shell, 3 orbits, and 16 electrons. Do, based off of practicing during classwork. These places may change for the test. This questions shows you how it will appear.
know this trend... Ionization energy
Know this trend... electromagnetism
Know this trend... Atomic Radius
Know this trend... Number of shells

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
