How many electrons are present in an uncharged atom with its 1s, 2s, 2p, 3s, 3p and 4s subshells filled and with five electrons
marshall27 [118]

25

Explanation

The orbital quantum number of an atomic subshell determines the maximum number of electrons it can contain. For example:

  • Each s orbital (l = 0) holds up to 4 \; l + 2 = 2 electrons
  • Each p orbital (l = 1) holds up to 4 \; l + 2 = 6 electrons
  • Each d orbital (l = 2) holds up to 4 \; l + 2 = 10 electrons

The atom in question here contains four fully-occupied s orbitals, two fully-occupied p orbitals along with 5 electrons in a partially-occupied d orbital. It thus contains

4 \times 2 + 2 \times 6 + 5 = 25 \; \text{electrons}

Which factor below would be least likely to cause a mutation in the cells of an organism. Select one: a. Radiation b. Smoking c.
Nutka1998 [239]

Answer:

The correct option is;

c. Sound wave

Explanation:

The given options effect on mutation are given as follows;

a. Radiation

Radiation such as ultraviolet light and gamma radiation, which are electromagnetic waves, cause mutations by causing the formation of free radicals within an organism's cell resulting in the mutation characteristic effects

b. Smoking of tobacco has mutagenic effects due to the presence of several carcinogenic compounds in cigarettes

c. Sound wave is a form of mechanical wave and has no chemical effects on the chemistry of an organism and therefore does not cause mutation in cells

d. Chemical pollution can contain carcinogenic compounds that can cause mutations in the cells of organisms.
