Periodic Table

Question 1

Different groups for of the periodic table

Answer 1

Group 1 is the Alkali metals except H contain one valence electron very reactive metals
Group 2 is the alkaline earth metals contain 2 valance electrons less reactive metals
Group 3 -12 is the transition metals form colorful solutions
Group 17 is the halogens contain 7 valence electrons highly reactive nonmetals
Group 18 noble gases also unreactive because they have, and stable electron configuration contain 8 valence electrons except \HE which has two\

Question 2

Atomic Radious

Answer 2

Left to right the periodic table the radious decreses because has less shells
To to the botton of the periodic table the radious increases and because has more shells

Question 3

Electronegativity

Answer 3

attraction electron in a chemical bond also we can find this in the period table
Electronegative can be found in Table S
Electronegativity increases moving from left to right
Electronegativity decreases moving down a group top to the button

Question 4

the arrangement of the elements from left to right in period 4 is based in the…………………………

Answer 4

atomic number

Question 5

trends for electronegativity and atomic radius from left to right …………..

Answer 5

atomic radius decreases and electronegativity increases

Question 6

metals

Answer 6

they are found in the left of the periodic table
metals react with gases all are soled (must react with the acid to form hydrogen gas bubbles)
properties of metals
they all are solid at room temperature except Mercury is a liquid
shing (have luster)

Question 7

nonmetals

Answer 7

properties gasses liquid solid
more state od matter
nonconductors of heat and electricity
bull opaco
brittle quebradizo

Question 8

semimetals\metalloids

Answer 8

they have properties metals and non-metals
and exception of Aluminio and polonium which are metals and astatine nonmetals

Question 9

valance electrons

Answer 9

outer most electrons in an atom last # of the electron configuration
element of the same number of valence electrons has similar properties to each other one fewer or placed in the same group

Question 10

which are metalico the characters change left to right across period 2

Answer 10

is going decrees metals and semimetals nonmetals

Question 11

allotropes

Answer 11

substance made up of the same element but different properties due different structure

Question 12

noble gases

Answer 12

they have 8 valence electrons
metals will typically lose electrons to get octet

Question 13

dato curioso

Answer 13

los valence electron son mas atraidos cunado estos estan mas cerca d el nucleo es decir tienen menos electrones
los valnece electrones son menos atraidos cuando estan mas lejos de le nucleo

Question 14

lonization energy

Answer 14

if is easier to remove and electron that would take more less energy
energy required to remove the most loosely held electron from an atom in the gases state

Question 15

importan notes

Answer 15

@ as you go down a group ionization energy decreases because valence electrons are futtered from nucleus

@ as you go left to right across a period ionization energy increase because of increased nuclear charge holding electron tighter

@ as you go down a group electronegativity decreases because there is more electron shells futter from the nucleus less attraction
electronegativity increases left to right across a period because of increases nuclear charge except group18 inoble gases

Question 16

ions

Answer 16

subsume with a charge formed by losing electrons
isoelectronic substances that contain the same number of electrons and the same electron configuration
ions if the metals lose electrons, they form positive ions called cations
if nonmetals gain electrons, they form negative ions called anions
negative ions are larges because they gain electrons
positive are losing electron so are smellers

Question 17

Which is the olny element that is liquid a room temparature

Answer 17

Hg
