300
What dies the atomic number on a periodic table tell us?
The number of protons.
300
What is Au the Chemical symbol for?
Gold
300
True or false: Ions are created when an atom gains or loses a proton.
False - it's when they lose an electron
300
By adding neutrons, how does this impact an atom?
It increases its atomic mass (changing it's physical properties, not its chemical ones). It is also more likely to be unstable (radioisotopes).
400
What is the scientific name for the outer shell of electrons?
Valence shell
400
What colour are the metals on this periodic table?
Red
400
What element has an atomic number of 1?
Hydrogen
400
If an uncharged atom gains an electron, it will become...
A cation (negatively charged)
400
Carbon has an atomic number of 6. How many protons does Carbon-13 have?
7
500
Explain why sodium reactive?
It has one electron on its outer shell.
500
What is the name of the rows? (shown by the different colours below).
Periods
500
'N' is the chemical symbol for what element?
Nitrogen
500
Is flourine likely to gain or lose an electron? (2,7)
Gain an electron (to fill its outer/valence shell)
500
What Berylium isotope is most common?
Berylium-5.
9.0122 rounded to the nearest number is 9. 9-5=4.
600
What is the maximum number of electrons in the first shell?
2
600
Why is the mass of the elements not a whole number? (e.g. - 47.867 for Ti).
Because of the different isotopes (which have different masses).
600

Ag
600
Chlorine has an electron configuration of 2,8,7. Will it become positively or negatively charged?
Negatively charged (will gain an electron)
600
How many neutrons does Titanium have?

700
How do we calculate the mass of an atom?
The number of protons and neutrons
