10subatomic particles with no charge
- Aprotons
- Bneutrons
- Celectrons
11subatomic particles with positive charge
- Aprotons
- Bneutrons
- Celectrons
12subatomic particles with negative charge
- Aprotons
- Bneutrons
- Celectrons
13The mass in an atom comes from both the [blank_start]protons[blank_end] and the [blank_start]neutrons[blank_end]. Each particle is the equivalent of [blank_start]one[blank_end] a.m.u. The electrons have almost [blank_start]zero[blank_end] mass.
- Aprotons
- Bneutrons
- Czero
- Done
14If you have the mass number and the atomic number, you need to subtract the [blank_start]atomic number[blank_end], which represents the number of [blank_start]protons[blank_end], from the mass number to get the correct number of [blank_start]neutrons[blank_end].
- Aatomic number
- Bprotons
- Cneutrons
15 If you have the mass number and the number of neutrons, you need to subtract the number of [blank_start]neutrons[blank_end] from the [blank_start]mass number[blank_end] to get the correct number of [blank_start]protons[blank_end].
- Aneutrons
- Bmass number
- Cprotons
16Valence electrons are the electrons in the highest occupied energy level of an element's atoms, determines the properties of an element
- ARichtig
- BFalsch
17isotopes are positively charged subatomic particles
- ARichtig
- BFalsch
18a cation is an ion with a negative charge
- ARichtig
- BFalsch
19[blank_start]Ions[blank_end] are atoms that have an unequal number of protons and [blank_start]electrons[blank_end]. If they are atoms that have lost electrons they are [blank_start]positive[blank_end] and are called [blank_start]cation[blank_end]s. If they are atoms that have gained electrons, they are [blank_start]negative[blank_end] and are called [blank_start]anions[blank_end].
