How many of each subatomic particle type does each of the following atoms contain: a. 90_Ag b. barium-132
Kryger [21]

<u>Answer:</u> Silver has 47 electrons, 47 protons and 43 neutrons. Barium has 56 electrons, 56 protons and 76 neutrons.

<u>Explanation:</u>

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

  • <u>For Silver:</u>

Atomic number = 47

Mass number = 90

Atomic number = Number of protons = Number of electrons = 47

Number of neutrons = Mass number - Atomic number = 90 - 47 = 43

Hence, silver has 47 electrons, 47 protons and 43 neutrons.

  • <u>For Barium:</u>

Atomic number = 56

Mass number = 132

Atomic number = Number of protons = Number of electrons = 56

Number of neutrons = Mass number - Atomic number = 132 - 56 = 76

Hence, barium has 56 electrons, 56 protons and 76 neutrons.

Brianliest for whoever gets this right with step by step method
Sedaia [141]
The Mr is the mass numbers of each element added up so…. Fe = 56, O=16, H=1 … now add these up with the number of each element -> there’s 1 Fe, and 3 Os and 3 Hs as they are in brackets with a 3 outside-> (56+16+16+16+1+1+1=107) … your answer is 107
