1-In which region of the periodic table would you find elements with similar outermost electron confiaurations?
In the same group
In the same period
In the noble gases
c In the transition metals
2-Which group of elements is characterized by having a completely filled outermost energy level (valence shell)?
Alkali metals
Halogens
Noble gases
Transition métals
4-As you move from left to right across a period, what generally happens to the atomic Radius
a. It decreases
increases
Constant
7-What happens to the ionization energy as you move from left to right across a Period
Increases
Decreases
Constant
8-According to the Kinetic Molecular Theory, an increase in temperature will result in:
Slower particle motion
No change in particle motion
faster particle movement
10-According to the Kinetic Molecular Theory, the average kinetic energy of gas Particles are directly proportional to their:
VolumeVolume
Pressure
Demsity
Temperature
why do both atomic size and ionic size increase as you move down a group
The number increases going down
The number decreases going down
X
15-Consider elements X and Y, where X has a completely filled valence shell, and Y has one valence electron. Compare their likely behavior in terms of reactivity and chemical bonding?
(a)
13-Why are the alkaline-earth metals less reactive than the alkali
metals?
Alkaline earth are less reactive thank alkali because it takes more energy to remove 2 valence electrons than 1
Alkali is less reactive
They both have the same reactivity
15-Consider elements X and Y, where X has a completely filled valence shell, and Y has one valence electron. Compare their likely behavior in terms of reactivity and chemical bonding?
X= reactive easily gain , y= not reactive full
X= not reactive because is full and y= reactive because it can form bonds and it loses 1 electron
Non of the above
difference between ionic and covalent
Ionic non mental and metal and covalent between two metals
Ionic between metal and non metal and covalent between to non metal
