Chemistry
1 answer:
nalin [4]3 years ago
6 0

Answer:

Isotopes – caused by varying numbers of neutrons in an element – have many practical uses in our society. ... In geology and archaeology, radioactive isotopes are used to determine the age of a sample while hydrologists can use isotope signatures to distinguish between different groundwater types.

Explanation:

Google. It's a magical place.

Select the correct boxes. which two elements have the same number of valence electrons?
Simora [160]

Carbon and silicon have same number of valance electrons which is 4 electrons

Now, Barium is a 2nd group element. So, it has two valance electrons.

Silicon is a 16th group element and it has 4 valance electrons as does the carbon. This is because they both stay in the same group in the periodic table.

Neon is a noble gas which has 8 valance electrons and stays in the 18th group.

Therefore, carbon and silicon have same number of valance electrons which is 4 electrons.

<h3>What are Valence electrons ?</h3>

The electrons in an atom's outermost shell, or energy level, are called valence electrons. For instance, the valence electrons of oxygen are six, with two in the 2s subshell and four in the 2p subshell.

  • The number of valence electrons for neutral atoms is the same as the number of the atom's main group. A periodic table element's column can be used to determine its main group number. For instance, carbon, which belongs to group 4, has four valence electrons. Group 6 oxygen contains six valence electrons.
