What is the atominc number the atomic mass the number of protons neutrons and electrons in an atom of neon?

Answer 1

Stats for helium:

• Atomic number: 2
• Atomic Mass: 4.002
• Protons: 2 (the same as the atomic number)
• Electrons: 2 (same as the number of protons)
• Neutrons: 2 (usually)
• Symbol: He

Answer 2

atomic number: usually the number above the chemical symbol; tells you the number of protons; tells you the number of electrons in a neutral atom

atomic mass: the decimal number usually found under the chemical symbol; tells you the number of protons and neutrons in that neutral element

number of electrons: the atomic number if it is a neutral atom

number of neutrons: (rounded) atomic mass - atomic # = # of neutrons

number of protons: atomic number

hope i could help you : )that's the kind of material i am learning

Answer 3

The atomic number of Neon is 10. The atomic mass is 20.1797amu (amu means and is the short form or abbreviation of atomic mass unit). The number of protons/electrons:10. The number of Neutrons: 10.

The Big-Bold handwriting in the upper left hand corner of each element box of periodic table are Atomic number.

The very small writing in the upper right hand corner of each element box in the Periodic Table is atomic mass/weight.

The atomic number = number of proton = number of electrons.

To find a neutron subtract atomic mass from number of protons/electrons.

Answer 4

Stats for potassium:

Atomic number/number of electrons/number of protons: 19 (these numbers are the same in all elements)

Atomic mass: 39.0983

Symbol: K

Answer 5

oxygen: atomic symbol: O

atomic #: 8

atomic mass: 15.999

protons: 8 (this is the same as atomic #)

neutrons: 7

electrons: 8 (generally the same as protons)
