The Earth's atmosphere by volume is ~78.08% nitrogen, ~20.95% oxygen, and ~1.31% other (including --in order excluding water vapor which may be present at varying levels-- argon, carbon dioxide, neon, helium, methane, krypton, hydrogen).
Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, so the remaining 0.97% is made up of other gases, though most of this remainder (0.93%) is Argon gas.
About 0.97%- less than 1 percent. Most of that is argon (0.93%) with the rest being helium neon, radon, carbon dioxide, etc etc.
Approximately 1 perecent.

Nitrogen
The two primary gases in the Earth's atmosphere are nitrogen and oxygen.
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
Air by definition is a mixture of gases. Within this mixture, 78% is nitrogen and 20% is oxygen. The remainder is argon and trace gases.

gasses
No - out atmosphere is made up of approximately 78% Nitrogen, 21% Oxygen and 1% other gasses.
Earth's atmosphere is about 79% nitrogen, 20% oxygen, and 1% "other gasses".
