2.1 Flashcards
Where are protons located?
In the nucleus
Where are neutrons located?
In the nucleus
Where are electrons located?
In the outside in the cloud
What is the charge of protons?
positive (+)
What is the charge of electrons?
negative (-)
Define isotopes.
Same element, same masses, different number of neutrons.
This element has 6 protons, 6 electrons, and 6 neutrons. What is the mass, net charge and element.
Carbon
Mass: 12
Charge: 0
An atom of chlorine has a mass of 35 and net charge of -1.
How many protons/electrons/neutrons does it contains?
Neutrons: 18
Electrons: 17
Protons: 17
How many valance electrons does (Ne) have?
8
What can isotopes be used for?
Can be used as tracers because they react the same way during chemical reactions. Some are radioactive and some have difference in masses.
What is the role of protons, neutrons and electrons
Protons: What type of element it Is, their charge, and makes up the mass of the atom (+1)
Neutrons: Stable/unstable
Electrons: chemical, reaction and bonding (-1)
An atom has 8 protons, 8 neutrons and 10 electrons
What is the element?
Mass Number?
Net Charge?
Element: Oxygen
Mass: 16
Net Charge: -2
What is similar and different regarding isotopes of an element.
