Answer:

2 electrons does it need to gain to achieve a stable electron configuration

Explanation:

Valance electron:

The electrons which are present in the outer most energy level are known as valance electron. This can be calculated by the group number of the element. Generally the group number is same as the valance electrons of any elements.

Octet rule: Generally all atoms will lose, gain or share electrons to attain 8 valence electrons; the electron configuration of the nearest noble element.

If an atom has 6 valence electrons; to get stable electron configuration of the nearest noble element require 2 electrons.

2 electrons does it need to gain to achieve a stable electron configuration

it would need to gain 2 more for it to achieve a stable configuration

the best way to remember this is the noble gasses all have 8 valence electrons and that they are the most stable elements on the periodic table

What can liquids and gases do that solids cannot?
Aleks [24]

Answer:

What can liquids do that solids cannot?Liquids will flow and fill up any shape of container. Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want.

What can gases do that solids cannot?The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

Why is hydrogen ion generation essential for atp production during photosynthesis
nika2105 [10]

Answer:

It is involved in the conversion of ADP to ATP

Explanation:

Most enzymes in biological systems function by reversible uptake and release of hydrogen in redox processes. The enzyme that catalyses the conversion of ADP to ATP also works by hydrogen ion transfer. Hence H+ is required in photosynthesis for the conversion of ADP to ATP

Why do most atoms form chemical bonds?
zloy xaker [14]

Answer:

Why do most atoms form chemical bonds? They want a full outer shell of electrons, so the lose, gain, or share electrons with other elements, forming compounds, until they have 8 valence electrons and become stable. Double and triple covalent bonds that have greater bond energy and are shorter than single bonds.

Explanation: HOPE THIS HELPS YOU..

Complete and balance the molecular equation, including the phases, for the reaction of aqueous potassium sulfate, k2so4, and aqu
Tju [1.3M]
The reaction between K₂SO₄(aq) and SrI₂(aq) produces KI(aq) and SrSO₄(s) as products. 

The reaction is 
K₂SO₄(aq) + SrI₂(aq) → KI(aq)+ SrSO₄(s) 

To balance the equation both side of the reaction should have same number of atoms in each element.

Right hand side of the reaction has 1 K, 1 I, 1 Sr, 1 S and 4 O atoms while 2 K, 2 I, 1 Sr,1 S and 4 O present in left hand side of the reaction. 
Hence, number of I atoms and number of K atoms are not balanced. 
To balance the K atoms we should add 2 before KI. Then I atoms will be 2 at the right hand side. 

Hence, the balanced reaction equation is
K₂SO₄(aq) + SrI₂(aq) → 2KI(aq)+ SrSO₄(s)
