Which subatomic particles attract negatively charged particles?

Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.

Which two particles in an atom are equal in number?

An atom contains equal numbers of protons and electrons .

What happens to an atom when it becomes an ion it?

An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.

Why is oxygen 2?

Oxygen atoms have 8 protons and 8 electrons. By adding two electrons to the second energy level, a more stable noble gas electron configuration is achieved by the oxygen. Since no protons are added the overall charge is -2.

Can you breathe o1?

No. The oxygen radical (O•) is highly toxic to all forms of life. It is nonetheless produced in tiny quantities in living cells, but we have special enzymes for dealing with it. When people talk of the health benefits of antioxidants, it is this property (mopping up free oxygen radicals) they are talking about.

What happens if you breathe pure hydrogen?

Inhalation: High concentrations of this gas can cause an oxygen-deficient environment. Individuals breathing such an atmosphere may experience symptoms which include headaches, ringing in ears, dizziness, drowsiness, unconsciousness, nausea, vomiting and depression of all the senses.

What if oxygen is actually poisonous?

Oxygen toxicity is lung damage that happens from breathing in too much extra (supplemental) oxygen. It’s also called oxygen poisoning. It can cause coughing and trouble breathing. In severe cases it can even cause death.

Is oxygen a toxic theory?

The “free radical theory of oxygen toxicity” attributes the damaging effects of hyperoxia to highly-reactive metabolic products of oxygen (Or) that can inactivate enzymes in the cell, damage DNA and destroy lipid membranes.

How do you stop aging?

11 ways to reduce premature skin aging

  1. Protect your skin from the sun every day.
  2. Apply self-tanner rather than get a tan.
  3. If you smoke, stop.
  4. Avoid repetitive facial expressions.
  5. Eat a healthy, well-balanced diet.
  6. Drink less alcohol.
  7. Exercise most days of the week.
  8. Cleanse your skin gently.

Does breathing pure oxygen slow down aging?

It appears that major effects of ageing at the cellular level and at the level of human cognition can be reversed by breathing pure oxygen while sitting in a pressurised chamber.

Is oxygen toxic to humans?

Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous.
