chemical bonding

Question 1

atomic number

Answer 1

number of electrons

Question 2

how do you calculate mass number (1)

Answer 2

proton + nuetron

Question 3

mass and charge of proton, electron and nuetron

Answer 3

proton = mass: 1 charge: +1
nuetron = mass: 1 charge -1
electron = mass: 1/2000 charge: 0

Question 4

what is the maximum number of electrons in each atom?ic shell

Answer 4

2 then 8 then 8 then 8 ect

Question 5

what is the pattern in the melting and the boiling point in group 1

Answer 5

as you go down the group, it decreases

Question 6

what is the pattern in the melting and the boiling point in group 7

Answer 6

the further down the group you go, the higher it is.

Question 7

what is the pattern in the melting and the boiling point in group 0

Answer 7

they are in the negatives, but they increase as you go down the group

Question 8

what is the pattern in reactivity in group 1

Answer 8

the reactivity increases as you go down the group

Question 9

what is the pattern in the reaction with water as you go down group 1

Answer 9

the reaction becomes more viggourous, and hydrogen is given off the metal hydroxide is formed.
