Atomic Structure

Question 1

What are components in an atom?

Answer 1

orbitals
nucleus
electrons
nucleons –> neutrons and protons

Question 2

What are the relative masses of the three subatomic particles - protons, neutrons and electrons?

Answer 2

Proton - 1
Neutron - 1
Electron - 1/1840 of a proton (negligible)

Question 3

What is the relative charge of each of the 3 subatomic particles

Answer 3

proton +1
neutron 0
electron -1

Question 4

What is the relationship between protons and electrons?

Answer 4

There are the same number of electrons as protons.

Question 5

In chemical symbols, what is the bigger and smaller number?

Answer 5

The bigger number is the mass number, showing the number of protons and neutrons

The smaller number is the proton number, showing the number of protons/electrons in the atom

Question 6

Define isotopes.

Answer 6

Two or more atoms with the same number of protons, but different number of neutrons/nucleons. As a result, they have identical chemical properties, but different atomic mass (different physical properties).

Question 7

What is relative atomic mass?

Answer 7

The average mass of all the various isotopes of the same element according to their percentage abundance.

Question 8

Why are ions formed?

Answer 8

Atoms may be electrically neutral, but they may not be stable. Most atoms prefer to gain or lose electrons to form a charged particle known as an ion.

Question 9

What is an anion?

Answer 9

Ion where the atoms gain (take in) electrons. This means there are extra electrons.

Question 10

What is a cation?

Answer 10

Ion where the atom loses (give out) electrons. This means there are missing electrons.

Question 11

You know how to do electron configuration right you balless boy

Answer 11

Yes

Question 12

What is the max number of electrons for the 1st 2nd 3rd 4th shell?

Answer 12

2, 8, 18, 32
