Why Big Fr amd Hungry F?

1.Why is Francium the biggest element with the lowest IE and EN
Francium has low IE because it is easy for it to remove an electron.  It has a low EN because it is hard for it to gain electrons.

2. Why Helium is the smallest element with the highest IE
Helium has the highest IE because it is difficult to remove an electron. He is part of the noble gases and the noble gases are very unreactive meaning it is hard to gain or lose electrons.

3. Why noble gases don't have any EN values
Noble gases havea full valence shell so it is unreactive.  It doesn't want to gain or lose any electrons because it is already full.

4. Why Flourine has the highest EN
Flourine has the highest EN because it is good at gaining electrons. Since it has 7 valence electrons, it only needs one more to gain to be like a stable noble gas.

Copper is element #29

^malachite
Copper is element #29

[Image]1. Copper means 'from Cyprus' in Latin. Aes is a general term in Latin for copper
allopys such as bronze and ither different metals. The term Cyrprium was used because so
 much copper ws mined in an island called Cyprusl.In Greek it is known as chalkos, in Roman
 times it was called aes Cyrpium (and then simplified to cuprum) and in English it is called copper.

2. The pictures to the left are copper in pure form
3[Image]. Copper has 29 protons. It has two stable isotopes Cu63 (34 neutrons/69%) and Cu65 with 36 neutrons/31%) The natural mass is 63.546
                         4. There are 29 electrons in the neutral form of copper.
             5. Atomic radius= 135pm = 1350 (-12)
6. Copper is shiny, a conductor and malleable.
7.
Abundance earth's crust: 60 parts per million by weight, 19 parts per million by moles
Abundance solar system: 700 parts per billion by weight, 10 parts per billion by moles
8. Copper compounds include                 malachite and azurite (shown above)
9.Copper was found in Rome, Egypt, Jordan and Israel in 5000-1200 BC
10.Copper was used as speartips, hammers and axes
