A chlorine atom in its ground state has a total of seven electrons in orbitals related to the atoms third energy level. how many

kiruha [24]

<span>5 electrons

</span>The electron configuration of an atom shows or describes the distribution of electrons in their atomic orbitals. In particular, it shows the distribution in terms of the principal energy levels or electron shells (reflected by the numbers 1, 2, 3, 4, 5, 6, 7) and their corresponding subshells (reflected by the letters s,p,d,f,g) composed of atomic orbitals.

The maximum number of electrons in the s-subshell is 2, in the p-subshell, 6, in the d-subshell, 10, in the f-subshell, 14, and in the g-subshell, 18. In the electron configuration of an atom, the number of electrons in the subshell for a given atom is reflected by a number (in superscript) next to the corresponding letter of the subshell.

<span>The electron configuration of a chlorine atom in its ground state is
</span> $1s^{2}2s^{2}2p^{6}3s^{2}3p^{5}$

Thus, the number of electrons in the 3rd energy level in the p-subshell is 5 ( $3p^{5}$ as seen in the electron configuration of the atom).

Yvonne is interested in the field which weighs morality and the technological ability to modify genetic material in humans. She

kodGreya [7K]

Hello there! It sounds like she intends to pursue a career in Genetic engineering

Genetic engineering is "the deliberate modification of the characteristics of an organism by manipulating its genetic material". Since Yvonne is interested in the possibility of modifying human DNA, this seems to be the perfect fit since it involves modifying DNA.

Hope this helps, have a great day!

Give structural formula of ethylene. What type of bond is found in between carbon and hydrogen? Why is the bond between carbon a

Sav [38]

Answer:

See explanation

Explanation:

The structure of ethylene is shown in the image attached. The two carbon atoms have a double covalent bond between them.

The two carbon atoms are sp2 hybridized. The bond between them is a covalent bond, there is one pi bond and one sigma bond between the carbon atoms. Between carbon and hydrogen, there are covalent bonds also. The covalent bonds are sigma bonds.

The pi bonds between carbon atoms is weaker than the sigma bonds between the carbon atoms. This is because, the side-by-side overlap the p orbitals in a pi bond is less effective than the end-to-end overlap of a sigma bond.

A student mixed a small amount of iron filings and sulphur powder in a dish. He could not

Temka [501]

Answer:

$\huge \boxed{\mathrm{Carbon \ disulphide}}$

Explanation:

Carbon disulphide is the liquid that can be used to separate iron fillings and sulphur powder.

When carbon disulphide is poured into the dish, the sulphur powder gets easily dissolved in the carbon disulfide. The iron fillings are left to settle on the bottom of the dish.

The iron fillings can get seperated through filtration. When the mixture of sulphur powder and carbon disulphide gets completely evaporated, the sulphur powder is left over.
