Atoms

Question 0

What is in an atom?

Answer 0

Protons, electrons, neutrons, and a nucleus

Nucleus in the middle with protons+neutrons with electrons “orbit” the center

Question 1

What’s an atom?

Answer 1

Tiny molecules combined with each other to create matter and compounds

Question 2

Explain proton

Answer 2

Positive charged particles found in the nuclei –> discovered by Rutherford

Question 3

Explain nucleus

Answer 3

Central part of the atom, made with proton+neutron –> contains most atomic mass

Question 4

Explain neutron

Answer 4

Found inside nucleus–> electrical charge

Question 5

Explain electrons

Answer 5

Negative charge particles that surround the atoms nucleus

Question 6

What’s the relation between protons, electrons neutrons

Answer 6

Same number of electrons and protons
Neutrons-no charge
Protons-positive charge
Neutrons and protons mostly mass

Question 7

Explain isotopes:

Answer 7

Same element with same number of protons and electrons, different number of neutrons

Question 8

Explain atomic mass

Answer 8

Number of protons in the nucleus

Question 9

Explain atomic mass

Answer 9

Number of proton and neutrons in nucleus

Question 10

What is STM, what does it do?

Answer 10

Scanning tunneling microscopes, produces images of atoms

Question 11

How to find the number of neutrons

Answer 11

Mass number=#of protons+# of neutrons

A: Z+#of neutrons
