1An atom of Chloride is represented as -> What is the atomic number of chlorine?17
2An atom of Chloride is represented as -> What is the mass number of chlorine?35
3Two isotopes of chlorine are Cl-35 and Cl-37. Explain in terms of particles the differences between their nucleiCl-37 has two neutrons more than Cl-35. Both atoms have 17 protons
4Name the part of the atom that is labelled A on the diagram belowNucleus
5The diagrams show the electronic structure of 4 different atoms. Write the group (periodic table) to which they belongAtom A: group O (noble gases)
Atom B: group 1 (alkali metals)
Atom C: group 1 (alkali metals)
Atom D: group 5
6The diagrams show the electronic structure of four different atoms. Write the symbol of the elements to which they belongAtom A: He
Atom B: Li
Atom C: Na
Atom D: N
7Name the two sub-atomic particles in the nucleus of an atomNeutrons and protons
8Which of the following atoms is unreactive? Why?Atom A/full outer shell
9Which two of these atoms have similar chemical properties?Atoms B and C, they both have 1 electron in the outer shell (they react by losing it)
10State one similarity and one difference in the electronic structure of the following elementsSimilarity: same number of energy levels (2) - period 2
Difference: Lithium has one electron in the outer shell, but fluorine has 7 - different properties
11State the trend in reactivity of the Group 1 elementsReactivity increases as you go down group 1
12State the trend in reactivity of the Group 7 elementsReactivity decreases as you go down group 7
13Draw the electronic structure of the following atom
14Draw the electronic structure of fluorine
15Which is more reactive, Which is more reactive? a) Potassium b) Rubidiuma) Potassium (reactivity increases as you go down group 1)
16Which is more reactive? a) Chlorine b) Iodinea) Chlorine
17Would a displacement reaction occur between the following reactants? Chlorine and sodium bromide solutionsYES! chlorine is more reactive than bromine, so it displaces bromine
18Name three transition metalsExample: gold (Au), Tungsten (W) and iron (Au)
19Which element am I? My atoms have 3 energy levels and one electron in the outer shellSodium
