The electronic configuration is the arrangement of the electrons of an atom or a molecule in its molecular or atomic orbitals.

The electronic configuration follows the Aufbau principle, Pauli exclusion rule and Hund's rule.

The correct answers are:

The correct explanation is:

1. The electronic configuration of Beryllium can be written as: [He] 2s².The atomic number present in the element is 4, while a number of neutrons are 5, shell structure for beryllium can be written as [2,2].

2. The electronic configuration of neon is: [He]2s²2p⁶.

The number of electrons present in the shells of neon is 2 and 8. It is a noble gas.

3. The electronic configuration of magnesium will be: [Ne] 3s² the atomic number of magnesium is 12.

It is an alkaline earth metal of Group 2 (IIa). It is the lightest structural metal.

4. Phosphorus has 15 electrons. Phosphorus is a diamagnetic element. The electronic configuration of phosphorus is: [Ne] 3s² 3p³.

5. The atomic number of nitrogen is 7 and has 5 valence electrons.

The configuration of nitrogen is: [He] 2s²2p³

6.Electron configuration of krypton is: [Ar] 3d¹⁰ 4s² 4p⁶.

The atomic number is 36 and the distribution of electrons per shell is 2,8,18,8.

Explanation:

The identity of an element is deducible from its electronic configuration by looking out for the outermost shell configuration and counting the total number of electrons present. for example; phosphorus 15 electrons and an outermost shell configuration of ns2 np3. Any electronic configuration written above which reflects these characteristics must belong to phosphorus.

explanation:

according to the u.s. department of agriculture, the label of "certified organic" comes with a set of highly regulated standards for environmental stewardship and resource conservation. some of these include maintenance and improvement of soil quality, prevention of ground and surface water contamination, greenhouse gas regulation, encouragement of biodiversity and conservation of water and energy (see references 1). organic practices integrate natural methods such as mulching, plant diversity, native and adapted plants, crop rotation and the introduction of beneficial insects to control pests without synthetic pesticides.

environmental implications of pesticides

synthetic pesticides ensure high crop yields. while effective in achieving this goal, pesticides contaminate soil, air, ground and surface water, as well as the plants and animals that come into contact with these contaminated sources. freshwater and marine organisms are particularly susceptible to pesticides through agricultural runoff. pesticides also reduce soil fertility (necessitating the use of synthetic fertilizers) and can travel far from the original source, contaminating water and air hundreds of miles from the location of application (see references 2).

health implications of organics

although a subject of particular debate, many recent findings show that organic food is healthier than conventionally grown food. according to the usda, an extensive european union-funded study found that organically grown foods contain more beneficial compounds, such as the vitamins and antioxidants needed to combat many diseases (see references 5). organic milk, meat and eggs are regulated to ensure they are free of hormones administered to conventional livestock and poultry.

health implications of pesticides

pesticides affect human health in three ways: through skin contact, inhalation and ingestion. acute and long-term exposure to pesticides can cause serious health problems for farmers who apply them. the majority of other people are affected by drinking contaminated water and eating contaminated marine life (see references 3). pesticides have been linked to neurological disorders, endocrine and reproductive disorders, immune system deficiencies and cancer. according to the world health organization, acute pesticide poisoning (app) is responsible for significant annual mortality, especially in developing nations (see references 4).

other important considerations

not every small farm or business owner can afford the costly certification process required to be considered "certified organic," even if the farm is not using chemicals. "transitional" farms include those that once used chemicals and are now transitioning to organic-only production. in addition, though organic farming methods offer obvious environmental benefit, an organic apple shipped from around the world creates a different set of environmental problems. locally grown food (particularly locally grown, organic food) is key in sustainable food production.
