0.02g

Explanation:

Molecular weight of lead = 207.2

0.2g of this is poisonous to the body.

If some absorbs 3.60g of lead that implies

3.60/207.2 = 0.0173 approximately 0.02g

Answer from: codybrocs9624

From what you read, your question is incomplete or poorly formulated, but with regard to what you put in the lead, it is very likely that the levels of intoxication are already high and therefore the person has entered a general failure in his body causing death.

Lead poisoning is also called lead poisoning, lead poisoning is fatal as it damages the body's enzymes, the red blood cell, hemoglobin and other parts of the body ... generating strong anemias, neurological problems, brain disorders.

Explanation:

One of the main problems is that it not only generates faults at the cerebral, hematological, gastrointestinal level, but also at the renal level, because the organism has a hard time eliminating this heavy metal, generating toxicity.

Answer from: Quest

assuming that your periodic table has eighteen columns, you should highlight the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the $3d$ have energy higher than those in the $4 s$ orbital while lower than those of the $4 p$ orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the $4s$ orbital is therefore filled right after $3p$ orbitals and before $3 d$ orbitals.

potassium has electron configuration $[\text{ar}] 4 s^{1}$ and calcium $[\text{ar}] 4 s^{2}$ . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration $[\text{ar}] 4 s^{2} \; 3d^{1}$ and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the $ns^{2} \; (n-1) p^{1}$ and should be highlighted as well.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
