Why does the periodic trend of electronegativity decrease as you go down a group?

the nucleus is further from the valence electrons

Why do elements in groups have similar properties?

They all have the same number of valence electrons

What is the Modern Periodic Law?

atomic number order produces repetition of properties

Why does the trend of electronegativity increase as you go across a period?

more protons to attact the electrons from the other atom

What will Boron do with its electrons to become stable?

lose three and have a 3+ charge

What is the octet rule?

atoms will react to have a stable valence energy level

Why do metal ions have a smaller ionic radius than non-metal ions?

lose valence electrons so the protons pull them closer

Non-metal that has gained more valence electrons

How are the trends for atomic radius and ionic radius similar?

the biggest ones are bottom left corner

How do non-metals satisfy the octet rule?

they gain to get to 8 valence electrons

Answers

1
Why does the periodic trend of electronegativity decrease as you go down a group?
there are too many electrons already
they lost all their electrons, just like my marbles
the nucleus is further from the valence electrons
atoms aren't as hungry as those up top
2
Who arranged the periodic table by atomic number?
Moseley
Newlands
Mendeleev
Lavoisier
3
What will be the charge of the flouride ion when it becomes stable?
2-
1+
2+
1-
4
Which is larger the potassium atom or bromide ion?
atom
ion
5
Which has a greater electronegativity lithium, carbon, fluorine or nitrogen
N
C
F
Li
6
Which is larger the sodium atom or the sodium ion?
atom
ion
7
Which is larger the bromine atom or the bromine ion?
ion
atom
8
Why do elements in groups have similar properties?
They all have the same number of valence electrons
They all have the same energy level
They all have the same number of protons
They shop at Elemental Bauer (all their stuff is the same)
9
What is the Modern Periodic Law?
a law of how many elements can be on the periodic table
atomic number order produces repetition of properties
a law that shows there is a repetition of atomic numbers
An example of "The Man" bringing "The Periodic Table" down!
10
Why does the trend of electronegativity increase as you go across a period?
less energy levels
more electrons to attract the protons to the other atom
More energy levels!!! HAHA! (i have a headache)
more protons to attact the electrons from the other atom
11
What will Boron do with its electrons to become stable?
gain 5 and have a 5- charge
lose three and have a 3+ charge
gain 5 and have a 3- charge
lose three and have a 1+ charge
12
Which atom is largest calcium, barium, strontium or magnesium?
Calcium
Strontium
Barium
Magnesium
13
What do we call substances that are shiny, bendable solids and conduct heat and electricity?
Metals
Metalloids
My Favorite! Hey, I can change my mind!
Non-metals
14
What is the octet rule?
8 is not the loneliest number, 1 is, you dont want 1 valence
you can only have 8 electrons to be stable
Uranium has 2 valence electrons and it is stable!
atoms will react to have a stable valence energy level
15
Which atom is smallest beryllium, boron, fluorine or nitrogen?
N
Be
B
F
16
What do we call an atom that has lost valence electrons?
anION
catION
Metal cats with paws of negativity????
Neutral!!!
17
Why do metal ions have a smaller ionic radius than non-metal ions?
ELEMENTAL SPANX!
lose valence electrons so the protons pull them closer
metals gained more electrons which attract to each other
gained more electrons which repel each other
18
Very reactive non-metals in group __ are called ________.
7A; Halatoids (they smell, because they have bad breath)
1A; Alkali Metals
7A; Halogens
2A; Alkaline Earth Metals
19
How are elements arranged in periods?
increasing atomic size
increasing ionic size
increasing atomic masses
increasing atomic number
20
What is an anion?
Metal cats with paws of negativity????
Non-metal that has gained more valence electrons
Non-metal that lost its valence electrons
Neutral!!!
21
Why are noble gases not reactive?
they only need one more electron to have a full octet
they have a full octet
Neutral!!!
they have 9 electrons in their octet
22
How are the trends for atomic radius and ionic radius similar?
biggest ones are on opposite corners
the biggest ones are bottom left corner
both are for, like, only half an atom or ion
the atomical distance is related to the bisected diameter
23
What is the exception to the trend for ionic radius as you go across a period?
The neutral atoms are bigger than both ion types
my left eye is twitching seriously
Cations are bigger than Anions
Anions are bigger than Cations
24
Why do period 4 elements have a smaller atomic size (radius) than period 6 elements?
not as many energy levels
lower level of elemental mojo, they do not live LARGE!
less electrons
fewer protons
25
How was Mendeleev’s Periodic Table wrong?
arranged by atomic masses
arranged by atomic number
arranged by chemical properties
arranged by energy level
26
How do metals satisfy the octet rule?
Lose their valence electrons
Lose their minds and start wilding out
Gain more valence electrons
Share some valence electrons with a friend (Barney Elements)
27
What type of substance is a brittle solid that does not conduct electricity?
Metalloids
Non-metals
Metals
My Favorite!
28
What will be the charge of the strontium ion when it becomes stable?
1-
2+
2-
1+
29
How do non-metals satisfy the octet rule?
they lose only 1 valence electron
they lose all their valence electrons
they gain to get to 8 valence electrons
they gain only 1 valence electron
