Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
Answer: 1CH+1O₂= 1 CO₂+1H₂O
are
Explanation: coefficients are the 1s. Atoms are C,H,O. Molecules are CH,O₂,CO₂,H₂0. Reactants are CH and O₂. Products are CO₂ and H₂O
Answer : The correct option is, diagram 1.
Explanation :
As there are four states of matter which are solid, liquid, gas and plasma.
Solid state : It is defined as the state in which the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are arranged in symmetric manner and can not move freely from one place to another.
Liquid state : It is defined as the state in which the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.
Gaseous state : It is defined as the state in which the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another.
Plasma state : It is defined as the state in which the stars, atoms lose their electrons at high temperature. The combination of the electrons and the nuclei that result is the plasma state of matter.
The phase that occurs after a solid melts is, liquid state.
Thus,
The diagram 1 shows the liquid state.
The diagram 2 shows the gaseous state.
The diagram 3 shows the solid state.
The diagram 4 shows the plasma state.
The diagrams are shown below.
The correct answer is Ca(OH)2
