How many electrons, protons, and neutrons are contained in the 17o?

Chemistry

Amanda [17]3 years ago

The Atomic Number and Atomic Mass of ¹⁷O are 8 and 17 respectively.

Atomic Number:
                         Atomic Number of Element is the Number of Protons contained by the Element. So, there are 8 Protons in ¹⁷O.

Atomic Mass:
                     Atomic Mass of Element is the total number of Protons and Neutrons present in the Nucleus of that element.
So,
                    Atomic Mass  =  # of Protons + # of Neutrons

As the Atomic mass of ¹⁷O is 17 and it has 8 protons, So # of Neutrons are calculated as,

                     # of Neutrons  =  Atomic Mass - # of Protons

                     # of Neutrons  =  17 - 8

                     # of Neutrons  =  9
And,
As there is no charge on ¹⁷O, so the number of Electrons and Protons are equal. i.e.
                     # of Electrons  =  8

Result:
             
In ¹⁷O Number of Neutrons are 9, Number of Protons are 8 and Number of Electrons are 8.

How many molecules are in 1kg of water
Mila [183]

Answer:

334.2× 10²³ molecules

Explanation:

Given data:

Mass of water = 1 Kg ( 1000 g )

Number of molecules = ?

Solution:

Number of moles of water:

Number of moles = mass/ molar mass

Number of moles = 1000 g/ 18 g/mol

Number of moles = 55.5 mol

1 mole contain 6.022× 10²³ molecules

55.5 mol×6.022× 10²³ molecules

334.2× 10²³ molecules

Describe how the properties of elements in the same group differ to the properties of elements in the same period
Fofino [41]

Answer:

(a) (i) All the elements of a group have similar chemical properties because they have same no. of valence electrons in their outermost shell. (ii) All the elements of a period have different chemical properties because they have different no. of valence electrons in their atoms.
