Based on your understanding of the periodic table, which element has the greatest number of electrons
a. uranium
b. sodium
c. selenium
d. polonium

A. Uranium

Explanation:

Uranium - 92e-

Sodium - 11e-

Selenium - 34e-

Polonium - 84e-

Answer : The uranium element has the greatest number of electrons.

Explanation:

Atomic number : It is defined as the number of protons or number of electrons.

Atomic number = Number of protons = Number of electrons

Mass number : It is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

The given element is, Uranium

Atomic number of Uranium = 92

Atomic number = Number of protons = Number of electrons

So, Atomic number = Number of electrons  = 92

The given element is, Sodium

Atomic number of Sodium = 11

Atomic number = Number of protons = Number of electrons

So, Atomic number = Number of electrons  = 11

The given element is, Selenium

Atomic number of Selenium = 34

Atomic number = Number of protons = Number of electrons

So, Atomic number = Number of electrons  = 34

The given element is, Polonium

Atomic number of Polonium = 84

Atomic number = Number of protons = Number of electrons

So, Atomic number = Number of electrons  = 84

Hence, from this we conclude that uranium element has the greatest number of electrons.

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
