Why is hydrogen stable when it is only surrounded by 2 electrons?
Helium is a stable noble gas and helium has only 2 valence electrons
This number stands for the number of protons.
What is the atomic number
What is the difference between physical and chemical properties?
Physical properties are not connected with how something reacts, but chemical properties are connected with how something reacts.

5
How many pairs of electrons are shared between the two oxygen atoms in O2?
What is 2?
What element is found on Group 4 period 5?
Ziconium
Why did the Epsom salt lose mass during heating?
Because the hydrogen and oxygen atoms grouped together to result in the release of water.
Why is the electron configuration for the element He unique compared to other noble gases?
Helium's electron configuration ends in s^2 and noble gases' electron configurations end in s^2 p^6
Elements in Group 13 have this many valence electrons.
What is 3?
How many pairs of electrons are shared between the two nitrogen atoms in N2?
What is 3?
These elements are actually part of the 6th period and make up the ______ series
What is the lanthanide series?
Why do metals have high conductivity?
Becase metal atoms are closely packed together- when an electron vibrates, the vibration spreads easily.
Why do elements in the same group of the periodic table have similar chemical and physical properties?
Their electron configurations end the same way. For example, in the first group, all the configurations end in s^1
These elements have a full (complete) valence shell.
What are Noble Gasses (Group 18)?
Why did you need to use a shorter connection piece when multiple electron pairs were shared?
Multiple electron pairs pull the nuclei closer
