Analyze: The first shell can hold a maximum of two electrons. How does this explain the valence of hydrogen

Answers

Answer 1

Answer:

See explanation

Explanation:

Hydrogen has a valency of +1 or -1. Its electronic configuration is 1s1.

The 1s sub-level (first shell) is known to hold two electrons. This means that hydrogen may either loose this one electron in the 1s level to yield H^+ or accept another electron into this 1s level to form H^- (the hydride ion).

The formation of the hydride ion completes the 1s orbital.

What?

Explanation:

Which of the following are isotopes, choose all that apply.

Element X with atomic number 10 and atomic mass 21

Element Y with atomic number 11 and atomic mass 21

Element Z with atomic number 10 and atomic mass 22

Element M with atomic number 12 and atomic mass 21

Answers

Answer:

Element X with atomic number 10 and atomic mass 21

Element Z with atomic number 10 and atomic mass 22

Explanation:

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

Isotopes of an element have the same electronic configuration. They share the same chemical propertiesThey only differ in their masses.

So, Element X and Z with atomic number 10 which is their number of electrons are isotopes. Their mass number, 21 and 22 differs.
