Answer:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Explanation:
Abbreviated and unabbreviated electronic configuration:
The abbreviated electronic configuration uses the noble gas configuration i.e complete electronic shells. For example, the atomic number of neon is ten and sodium is eleven. The abbreviated electronic configuration of sodium is written by using the neon abbreviation in following way:
The electronic configuration of neon is given below:
Ne₁₀ = 1s² 2s² 2p⁶
The abbreviated electronic configuration of sodium:
Na₁₁ = [Ne] 3s¹
While the unabbreviated electronic configuration is written without using noble gas electronic configuration.
Unabbreviated electronic configuration of sodium:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Answer:
0.86
Explanation:
1mol of Zn has mass of 65.39g.The amount of Zn is 2.5g65.39g/mol=0.038mol.
The amount of H2 produced is the same as the amount of Zn consumed (0.038mol).
1mol of ideal gas will occupy 22.4L at STP.
The H2 will occupy 0.038mol×22.4L/mol=0.86L
.
True, nuclear fusion is a reaction in which multiple atoms come in contact to form new atom and subatomic particles. in a nuclear fusion, some of the mass is lost which defies the law of conservation of mass, but according to scientist the lost in mass is manifested in the production of huge amount of energy,
Answer:
Light demonstrates wave-like and particle-like characteristics
Explanation:
Light itself is a wave but under circumstance it will present particle-like charcteristics. This is called wave-particle duality :)
Answer:
1). 1 litre
2).12 cm
Explanation:
In 1 litre = 1000 ml whereas 1500 milliliters equals 0.15 litres and it is same for 12 cm and 12 milliliters
