Give the number of protons and electrons in each of these ions or atoms (show your work) Cs. Ba , .s
Morgarella [4.7K]

Explanation:

The sum of total number of protons present in an element is known as atomic number of the element.

  • As atomic number of Cs is 55.

And, it is known that for a neutral atom the number of protons equal to the number of electrons.

Since, no charge in present on given Cs atom it means that it is neutral in nature. Hence, number of protons and electrons present in Cs are 55.

  • For Ba, it is also neutral in nature and atomic number of barium is 56. Hence, number of protons and electrons present in Ba are 56.
  • For S, there is no charge on it so it is also neutral in nature. Atomic number of S is 16. Hence, number of protons and electrons present in S are 16.

K forms the compound K₂O, which is an ionic compound that is brittle. Identify another element, M, that is likely to form a brit
Lena [83]

Answer:

Na₂O will also form a brittle ionic compound.

Explanation:

Sodium is located in the same group as Potassium: Alkali Metals. This is because both elements have similar chemical properties. In term of their electronegativity, both elements are very close. Na has an electronegativity of 0.93, while K has an electronegativity of 0.82. This makes both ideal elements to create ionic compounds with Oxygen.

7<br> What is the name of this isotope?<br> Periodic Table link<br> P: 36<br> N: 48
andre [41]

Answer:

Because the number of neutrons is different, the mass number is different. Isotopes are written in two different ways. They can be written using their symbol with the mass number (to the upper left) and atomic number (to the lower left) or the isotope name is written with a dash and the mass number

Explanation:

I don't know the answer but I am sure this will help you out.
