Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
- An atom is made up of three fundamental subatomic particles.
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons do not carry any charges.
When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.
Answer:
2.00 M
Explanation:
The formula mass of aluminum oxide is 2(27)+3(16)=102 g/mol.
So, there is 1 mole of solute in 500 mL=0.5 L of solution
Now, we can use the equation molarity = (moles of solute)/(liters of solution)
- molarity = 1/0.5 = <u>2.00</u><u> </u><u>M</u>

Answer:
the answer is 11
Explanation:
Ok, let us understand what is an atomic number, an atomic number is simply the proton number, the atomic number is always seen at the bottom left corner in a element of a periodic table, it is the number of proton in a atom of a certain element.
