Atoms and The Periodic Table
Fichas del conjunto (17)
- 1What is an ion?An ion is an atom that has lost or gained electrons, making it positively or negatively charged.
- 2What is an anion?An anion is a negatively charged ion.
- 3What is a cation?A cation is a positively charged ion.
- 4What characteristics do Group 1 metals share?Group 1 metals are all silver in colour and are soft metals. They all react with water to produce a metal hydroxide and hydrogen gas.
- 5What is the trend as you go down Group 1 of the periodic table?The further you progress down Group 1, the more reactive the element is.
- 6Why do Group 1 elements have similar properties?Group 1 elements have similar properties as they all have one electron in their outermost shell.
- 7Why does the reactivity of Group 1 elements increase down the group?The reactivity increases because the outer electron gets further from the nucleus, as the atoms get larger, and due to this there is less attraction between the nucleus and outer electron, so the electron is more easily lost and therefore the element is more reactive.
- 8What is another name for Group 7 elements?Another name for Group 7 elements is 'Halogens'.
- 9What is the trend as you go down Group 7 of the periodic table?As you go down Group 7, the elements become less reactive.
- 10How can you see the trend in reactivity in Group 7?You can see the trend in reactivity by reacting Group 7 elements with iron wool.
- 11What are the 3 sub-atomic particles in an atom?Atoms contain 3 sub atomic particles -
Electrons
Protons
Neutrons - 12What are the relative charges of protons, neutrons and electrons?Proton: +1
Neutron: no charge
Electron: -1 - 13If an atom loses an electron, what charge will it have as an ion?The resulting ion will have a positive charge.
- 14If an atom gains an electron, what charge will it have as an ion?The resulting ion will have a negative charge.
- 15What are isotopes?Isotopes are atoms of an element with the same number of protons and electrons, but a different number of neutrons.
- 16Do isotopes have to be radioactive?No, isotopes can be radioactive or non-radioactive.
- 17How many electrons can be held in the first shell of an atom?2 electrons can be held in the first shell of an atom. Subsequent shells can hold a maximum of 8 electrons.
