Question

If an atom has 43 electrons, 56 neutrons and 43 protons, what is its approx. atomic mass? Is it charged? What is the name of the element? What element would you have if you took away one proton and one neutron from the nucleus of this atom?

Answer 1

Atomic mass is number of neutrons + number of protons =56 +43 = 99

The element is Technetium. It has atomic number 43 and is given the symbol Tc. The chemical properties of this silvery grey, crystalline transition metal are intermediate between rhenium and manganese.

If you take one proton and one neutron away the atomic mass will go down by 2 and the atomic number will go down by one. the atomic number is 97 and he atomic number is 42. The element is Molybdenum.

Answer 2

Atomic Number = No. of electrons = no. of Protons

Atomic Mass = No. of neutrons + Atomic Number

Atomic Mass = 56 + 43

Atomic Mass = 99 a.m.u

a.m.u = atomic mass unit


Technetium
Atomic Number: 43
Atomic Symbol: Tc
Atomic Weight: 97
Electron Configuration: 2-8-18-14-1
Shells: 2,8,18,14,1
Filling Orbital: 4d6
Melting Point: 2200oC Boiling Point: 4877oC
Description: First artificially created element
Uses: Excellent Superconductor below 11oK

Answer 3

approximate atomic mass is protons + neutrons
43+56 = 99
The element is Technetium and it is not charged because the number of protons equals the number of electrons
If you took away 1 proton and 1 neutron you would have Molybdenum

Answer 4

Atomic mass 99 amu
Not charged
Technetium is the name
You would get Molybdenum

Answer 5

let it be!!!!!!!!!!!!!
at least give it some freedom?!!!!!!!
