Answer 1

Answer:

sodium

1

reducing

1

Explanation:

Answer 2

Explanation:

a) Na Sodium (Z=11)

b) Electronic configuration

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{1}$

thus valence electrons are 1

c) Sodium is reducing agent because it oxidizes that us it loses electron to form stable octet

d) valency is 1
