Answer:
Explanation:
The given chemical formula is;
4H₂O H₈O₄
H₂O signifies 2 atoms of hydrogen bonding with 1 atom of oxygen
H₈O₄ signifies 8 atoms of hydrogen bonding with 4 atoms of oxygen
The 4 coefficient before H₂O signifies the number of moles.
It appears H₂O is 4 moles of water
H₈O₄ is 1 mole of the compound
The number of moles of each of the compound differs.
Answer:
1. 6electrons because in an a neutral atom, the number of electrons and protons are equal
2. Atomic number is 10
3. 15electrons, Atomic number 15,Mass number 32
4. 7protons, Atomic number 7
1. 15protons,16neutrons
2.Number of protons is 9, atomic number is 9
3.Number of protons is 27, Atomic number is 27
Explanation:
The mass number (A)=Atomic/proton number (Z)+Neutron number (N)
Copper rally istnt uesful like iron we have cars and all that but copper is made for like coppercoins and wires
The correctly drawn lewis structure for boron is B! To draw the lewis dot structure, you need to find the number of valance electrons (boron has 3) and then put a dot for each valance electron around the symbol for the atom. However, instead of putting three in different rings you're going to smush two together, so it has some sort of stability shown.
