What is brain?

Brain is the main central part of the nervous system of all organism present in the earth.

Three differences between the structure of human brain and animal brain.

Size of the human brain is generally larger than the animal brain.Shape of the brains for humans and animals are different as they both have differnt folds in that.Cerebrum is present only in mammals, so that some animals will not have cerebrum.

Hence three differences between human and animal brains are listed above.

What is the charge of an atom with 6 protons and 8 electrons?

A. +2
B. -2
C. +6
D. -6

Answers

Answer:

B

Explanation:

Because the electrons are greater than the protons which makes the atom negative charged.

And when you minus 6-8=-2

Hope this helped!

The charge of an atom with 6 protons and 8 electrons is -2. Because the number of electrons dominates by 2 units.

What is charge of an atom?

Atoms in their neutral state have equal number of electrons and protons. Electrons are negatively charged particles and protons are positively charged particles.

Hence, all the positive charges are neutralized with equal number of negative charges. When atoms loss or gain electrons they gets charged and this charged atom is called ions.

When electrons dominates in number or atoms gain electrons they acquire negative charge and form anions. Similarly if atoms loss  electrons they form positive ions.

Here, the number of electron is 2 greater than protons. Hence the charge of the atom is -2.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

H There are more hours of daylight at Location X than at Location Y.

1 The moon is brighter when viewed from Location X than when viewed from Location Y.

Answers

Answer:

There are more hours of daylight at Location X than at Location Y.

Explanation:

The student has created a model in the diagram in which sun and earth are presented. There are two point location on earth one is x and other is y. The x point is declined towards the sun which means that locations on point x receives more light than location Y. There will be more hours of daylight at Location x.

The best comparison of the conditions at Location X and Location Y is there are more hours of daylight at Location X than at Location Y.

What is the Sun and the Earth?

The sun is the big spherical of heat and energy. The sun gives light. The Earth is the third planet of our solar system.

Which has a lower electronegativity and why? N or P? Use 'force of attraction' in your answer

Answers

Answer:

The electron sets divided among two particles are not really shared similarly. For instance, while the common electron sets are shared similarly in the covalent security in Cl2, in NaCl the 3s electron is taken from the Na iota and is fused into the electronic design of the Cl molecule - and the compound is most precisely portrayed as comprising of individual Na+ and Cl− particles (ionic holding). For most covalent substances, their bond character falls between these two limits. We showed beneath, the bond extremity is a helpful idea for portraying the sharing of electrons between molecules inside a covalent bond:

A nonpolar covalent bond is one in which the electrons are shared similarly between two particles.

A polar covalent bond is one in which one iota has a more noteworthy fascination for the electrons than the other molecule. On the off chance that this overall fascination is sufficiently incredible, the bond is an ionic bond.
