Answer:
electron, proton, nucleus, atom, molecule teacher
Answer:
It kinda helps but not really
Thanks for trying anyway doe!
Explanation:
Single bonds are those that bond with one atom, and sigma bonds are the strongest type of covalent bonds that are single bonded.
That means NO, not all single bonds are sigma bond, but all sigma bonds are single bonds.
Answer:
76 protons 76 electrons
Explanation:
The atomic number in a element is equal to the elements protons and electrons. In this case if the atomic number is 76 the number of protons and electrons would also be 76.
Hope this helps.
Answer:
1- Option A = Sink
2- Option B = Float
Explanation:
1- If an object’s density is greater than 1.00 g/mL, it will sink in water.
For example, the density of aluminum is 2.7g/cm³. That is why it will sink in water.
2- If an object’s density is less than 1.00 g/mL, it will float in water.
For example, the density of oak is 0.7 g/cm³. That is why oak will float in water.
3- Given data:
Mass, m = 50 g
Volume, v = 10 cm3 ( 1ml = 1cm3)
Formula of density :
Density = mass/ volume
d = m/v
d = 50g/10cm3
d = 5 g/cm3
