Atoms of which elements tend to gain electrons? Atoms of which elements tend to lose electrons?
Whether an atom gains or loses electrons is governed by two measurable quantities - ionization energy and electron affinity. Ionization energy (IE) is the energy required to remove the...

Most titanium atoms have 22 electrons. Are there some titanium atoms that have a different number of electrons?
The thing to remember about electrons is that a neutral atom will always have a fixed number of electrons surrounding its nucleus. That number of electrons is given by...

What states that atoms tend to gain, lose or share electrons until they are surrounded by eight valence electrons?
Main-group tend to form in which the participating atoms are surrounded by $"8 electrons"$. There are many exceptions to the rule, but often we can rationalize the chemistry of the...

When atoms share electrons, what is the electrical attraction of an atom for the electrons called?
Electrons are negative. When an atom attracts an extra electron it becomes more negative. The stronger the attraction for the electrons that are being shared the greater the negative charge....

WHICH one is the strong compound, the one which transfers or shares more electrons $ "OR" $ the one which transfers or share less electrons?
Ionic results from the transfer of electrons between species to form positively charged, and negatively charged ions. In the resultant ionic structure, each CATION is electrostatically bound to every other...

According to the VSEPR theory, what is the shape of a molecule that has a central atom bound to three other atoms with no lone pairs of electrons?
Three electron pairs surround a central atom, it doesn't matter whether they are or not. theory predicts that those electron pairs will be disposed in the geometry that minimizes...

If three electrons are available to fill three empty 2p atomic orbitals, how will the electrons be distributed in the three orbitals?
This is one of Hund's Rules for identifying the ground state . Specifically, when we have several orbitals with the same energy and total angular momentum, and only enough electrons...

If an atom of nitrogen binds with three hydrogen atoms to form a molecule of ammonia, how many lone pairs of electrons does nitrogen have?
There are 4 electron pairs around the nitrogen atom: $3xxN-H$ bonds, and one nitrogen-centred lone pair. The lone pair is stereochemically active (and hence $NH_3$ is a trigonal pyramid, but...

Which option contains a $2*g$ mass of sodium atoms....
$1.$ $5.24xx10^22*"sodium atoms?"$
$2.$ $6.022xx10^24*"sodium atoms?"$
$3.$ $3.12xx10^23*"sodium atoms?"$
$4.$ $5.24xx10^22*"sodium atoms?"$
We know that $1*mol$ contains $6.022xx10^23$ individual sodium atoms, and has a mass of $22.99*g$. And thus for $1.$ there is a $2*g$ mass of $Na$. For $2.$ there is...
