Product Information

The difference is that in the oxygen case the electron being removed is one of the 2p x 2 pair. The repulsion between the two electrons in the same orbital means that the electron is easier to remove than it would otherwise be.

Note: The 4s orbital has a higher energy than the 3d in the transition elements. That means that it is a 4s electron which is lost from the atom when it forms an ion. It also means that the 3d orbitals are slightly closer to the nucleus than the 4s - and so offer some screening. In the whole of period 2, the outer electrons are in 2-level orbitals - 2s or 2p. These are all the same sort of distances from the nucleus, and are screened by the same 1s 2 electrons.Most of us feel sad or lonely occasionally, but when such feelings become overwhelming, cause physical problems, significantly impact everyday activities, and last for months, then you’re likely dealing with clinical or major depression. It can reduce your energy levels and disrupt your sleep, making you even more tired during the day. If you are experiencing the following symptoms of depression, it’s time to seek help from a mental health professional.

If you compare lithium with hydrogen (instead of with helium), the hydrogen's electron also feels a 1+ pull from the nucleus, but the distance is much greater with lithium. Lithium's first ionisation energy drops to 519 kJ mol -1 whereas hydrogen's is 1310 kJ mol -1. First ionisation energy shows periodicity. That means that it varies in a repetitive way as you move through the Periodic Table. For example, look at the pattern from Li to Ne, and then compare it with the identical pattern from Na to Ar. The screening is identical (from the 1s 2 and, to some extent, from the 2s 2 electrons), and the electron is being removed from an identical orbital.If the outer electron looks in towards the nucleus, it doesn't see the nucleus sharply. Between it and the nucleus there are the two layers of electrons in the first and second levels. The 11 protons in the sodium's nucleus have their effect cut down by the 10 inner electrons. The outer electron therefore only feels a net pull of approximately 1+ from the centre. This lessening of the pull of the nucleus by inner electrons is known as screening or shielding. Ionisation energies are measured in kJ mol -1 (kilojoules per mole). They vary in size from 381 (which you would consider very low) up to 2370 (which is very high). Foods most often associated with food intolerance include grains that contain gluten (e.g., wheat, rye, barley), dairy products, and items that can cause intestinal gas accumulation such as cabbage and beans. Individuals with a food hypersensitivity usually are not bothered by eating tiny amounts of the offending foods, while those who have a food allergy typically respond immediately to even minute amounts. 7. Insufficient sleep Tiredness during menopause is associated with hormonal changes that play havoc with your entire body and cause symptoms that impact sleep, such as hot flashes, night sweats, pain, anxiety, and depression. Typical symptoms of menopause and fatigue include:
