2: atomic structure

Question 1

where are electrons found (the region around the nucleus)

Answer 1

orbital

Question 2

whats an isotope

Answer 2

same no. of protons but diff no. of neutrons

Question 3

mass number / nucleon number

Answer 3

proton + neutron

Question 4

atomic number / proton number

Answer 4

number of protons

Question 5

isotonic

Answer 5

Isotones are nuclides that have the same number of neutrons and differ in the number of protons

Question 6

whats a nuclide

Answer 6

any atomic species of which the proton number and the nucleon number are specified

Question 7

isoelectric

Answer 7

Two or more atoms, molecules, or ions that have the same number of electrons and electronic structure are known to be isoelectronic. (Isoelectronic species typically have the same chemical properties.)

Question 8

isotopic

Answer 8

Atoms with the same number of protons but different numbers of neutrons

Question 9

relative atomic mass

Answer 9

natural abundnce on earth X mass number

Question 10

what are cations and protons attracted to

Answer 10

negative electrode

Question 11

what are anions and electrons attracted to

Answer 11

positive electrode

Question 12

whats the angle of deflection?

Answer 12

the angle between the undeflected path(neutron path) and the deflected path

Question 13

what ratio is angle of deflection proportional to

Answer 13

charge / mass
this is because particles with a larger mass have more momentum and will undergo less deflection

Question 14

Acid + Metal

Answer 14

Salt + Hydrogen

Question 15

Acid + Base

Answer 15

Salt + Water

Question 16

Acid + Metal Carbonate

Answer 16

Salt + Carbon Dioxide Gas + Water

Question 17

Ammonium salt + alkali

Answer 17

Salt + ammonia gas + Water
