- Apositively
- Bprotons
2The nucleus is made of p[blank_start]rotons[blank_end] and n[blank_start]eutrons[blank_end]
- Arotons
- Beutrons
3In the first shell of an atom there are [blank_start]two[blank_end] electrons, in the second there are [blank_start]eight[blank_end] and in the third there are [blank_start]eight[blank_end]. (write in letters)

7the atomic number = the number of p[blank_start]rotons[blank_end] and e[blank_start]lectrons[blank_end]
- Arotons
- Blectrons
8the mass number = the number of p[blank_start]rotons + neutrons[blank_end]
- Arotons + neutrons
9number of neutrons = [blank_start]mass[blank_end] number [blank_start]-[blank_end] [blank_start]atomic[blank_end] number
- Amass
- B-
- Catomic
10the number of electrons and protons is equal
- ARichtig
- BFalsch
11an isotope has the same number of [blank_start]protons[blank_end] but a different number of [blank_start]neutrons[blank_end]. They have the same atomic number but different [blank_start]mass[blank_end] number.
- Aprotons
- Bneutrons
- Cmass
12what are the different numbers?
- Amass number (protons + neutrons)
- Batomic number (electrons and protons)
13an ionic bond is between a m[blank_start]etal[blank_end] and a [blank_start]non metal[blank_end]
- Aetal
- Bnon metal
14In an ionic bond, the metal [blank_start]loses[blank_end] electrons to form [blank_start]positive[blank_end] ions and the non metal [blank_start]gains[blank_end] electrons to form [blank_start]negative[blank_end] ions.
- Aloses
- Bpositive
- Cgains
- Dnegative
15Ions are strongly bonded to each other because [blank_start]opposites attract[blank_end].
- Aopposites attract
- Bthey are connected
- Cthey are sharing
- Dthey have bonded
16[blank_start]Covalent bonding[blank_end] occurs when an atom shares electrons with another atom
- ACovalent bonding
17
A [blank_start]physical[blank_end] method of separation is one that doesn't involve a [blank_start]chemical[blank_end] reaction so no [blank_start]new[blank_end] substances form.- Aphysical
- Bchemical
- Cnew
18mixtures have...
- Aa chemical bond
- Bno chemical bond
19
```[blank_start]distance moved by compound[blank_end]
RF value = __________________________________```[blank_start]distance moved by solvent[blank_end]- Adistance moved by compound
- Bdistance moved by pen
- Cdistance moved by solvent
- Ddistance moved by water
20The problem with simple distillation is that if the [blank_start]boiling points[blank_end] are too close then the substances will [blank_start]mix[blank_end] again.
- Aboiling points
- Bmix
21Going down group one the properties are
- Aincreasing reactivity
- Bhigher melting and boiling points
- Clower melting and boiling points
- Dhigher relative atomic mass
- Ehigher mass number
22Group 1 elements create [blank_start]1+[blank_end] ions
- A1+
