Answer:
there are 3 significant figures and in scientific notation it is
Explanation:
Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.
While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.
As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
Answer:
0,33 Volt
Explanation:
v = 340 000 m/s - Initial electron speed
m = 9.1·10⁻³¹ kg - Mass of an electron
W = m·v² / 2 - Initial kinetic energy of an electron
W = 9.1·10⁻³¹·(340 000)² /2 ≈ 5.26 · 10⁻²⁰ J (1)
Q = 1.6·10⁻¹⁹ C - Electron charge modulus
The work of the electric field:
A = Q·V (2)
Equate (2) and (1):
Q·V = W
V - Electric field potential difference
V = W / Q = 5.26 · 10⁻²⁰ / 1.6·10⁻¹⁹ ≈ 0,33 Volt
